Thanks to cruisenotts for these little jems............

 

 

Three business men were sitting in a bar, drinking and discussing how stupid their wives were.

The first says, "I tell you, my wife is so stupid. Last week she went to the supermarket and bought $300 worth of meat because it on sale, and we don't even have a fridge big enough to keep it in!"

The second agrees that she sounds pretty thick, but says his wife is thicker. "Just last week, she went out and spent $17000 on a car," he laments, "and she doesn't even know how to drive!"

The third, a blond male, nods sagely and agrees that these two women sound like they both walked through the stupid forest and got hit by every branch.

However, he still thinks his wife is dumber. "I have to laugh when I think about it," he chuckles. "Last week my wife left on a vacation to Greece. I watched her packing her bags and she must have taken at least 5 boxes of condoms with her. She doesn't even have a penis.

A few minutes before the services started,the townspeople were sitting in their pews and talking. Suddenly, Satan appeared at the front of the church. Everyone started screaming and running for the entrance,trampling each other in a frantic effort to get away from evil incarnate.

Soon everyone had exited the church except for one elderly gentleman who sat calmly in his pew without moving, seeming oblivious to the fact that God's ultimate enemy was in his presence. So Satan walked up to the old man and

said "Don't you know who I am?"

The man replied, "Yep, sure do." "Aren't you afraid of me?" Satan asked. "Nope, sure ain't." said the man.

"Don't you realize I can kill you with a word?" asked Satan. "Don't doubt it for a minute," returned the old man, in an even tone.

"Did you know that I could cause you profound, horrifying, AGONY for all eternity?" persisted Satan. "Yep," was the calm reply. "And you're still not afraid?" asked Satan. "Nope," said the old man More than a little perturbed, Satan asked, "Well, why aren't you afraid of me?"

 

The man calmly replied, "Been married to your sister for 48 years." ************************************************************

Something to remember next time you're on holiday.......

Did you know....

The average blue whale produces over 400 gallons of sperm when it ejaculates, but only 10% of that actually makes it into his mate. So 360 gallons are spilled into the ocean everytime one unloads, and you wonder why the ocean is so salty......

Actually, That's not the reason why the sea is salty. If I may elaborate......

 

First, “fresh” water is not entirely free of dissolved salt. Even rainwater has traces of substances dissolved in it that were picked up during passage through the atmosphere. Much of this material that “washes out” of the atmosphere today is pollution, but there are also natural substances present.

 

As rainwater passes through soil and percolates through rocks, it dissolves some of the minerals, a process called weathering. This is the water we drink, and of course, we cannot taste the salt because its concentration is too low. Eventually, this water with its small load of dissolved minerals or salts reaches a stream and flows into lakes and the ocean. The annual addition of dissolved salts by rivers is only a tiny fraction of the total salt in the ocean. The dissolved salts carried by all the world’s rivers would equal the salt in the ocean in about 200 to 300 million years.

 

A second clue to how the sea became salty is the presence of salt lakes such as the Great Salt Lake and the Dead Sea. Both are about 10 times saltier than seawater. Why are these lakes salty while most of the world’s lakes are not? Lakes are temporary storage areas for water. Rivers and streams bring water to the lakes, and other rivers carry water out of lakes. Thus, lakes are really only wide depressions in a river channel that have filled with water. Water flows in one end and out the other.

 

The Great Salt Lake, Dead Sea, and other salt lakes have no outlets. All the water that flows into these lakes escapes only by evaporation. When water evaporates, the dissolved salts are left behind. So a few lakes are salty because rivers carried salts to the lakes, the water in the lakes evaporated and the salts were left behind. After years and years of river inflow and evaporation, the salt content of the lake water built up to the present levels. The same process made the seas salty. Rivers carry dissolved salts to the ocean. Water evaporates from the oceans to fall again as rain and to feed the rivers, but the salts remain in the ocean. Because of the huge volume of the oceans, hundreds of millions of years of river input were required for the salt content to build to its present level.

 

Rivers are not the only source of dissolved salts. About twenty years ago, features on the crest of oceanic ridges were discovered that modified our view on how the sea became salty. These features, known as hydrothermal vents, represent places on the ocean floor where sea water that has seeped into the rocks of the oceanic crust, has become hotter, and has dissolved some of the minerals from the crust, now flows back into the ocean. With the hot water comes a large complement of dissolved minerals. Estimates of the amount of hydrothermal fluids now flowing from these vents indicate that the entire volume of the oceans could seep through the oceanic crust in about 10 million years. Thus, this process has a very important effect on salinity. The reactions between seawater and oceanic basalt, the rock of ocean crust, are not one-way, however; some of the dissolved salts react with the rock and are removed from the water.

 

A final process that provides salts to the oceans is submarine volcanism, the eruption of volcanoes under water. This is similar to the previous process in that seawater is reacting with hot rock and dissolving some of the mineral constituents.

 

Will the oceans continue to become saltier? Not likely. In fact the sea has had about the same salt content for many hundred of millions if not billions of years. The salt content has reached a steady state. Dissolved salts are being removed from seawater to form new minerals at the bottom of the ocean as fast as rivers and hydrothermal processes are providing new salts.

 

We can summarize this discussion. Wherever water comes into contact with the rocks of Earth’s crust, either on land or in the ocean or within the oceanic crust, some of the minerals in the rock dissolve and are carried by the water to the ocean. The salt content of seawater does not change because new minerals are forming on the sea floor at the same rate as salt is added. Thus, the salt content of the sea is at steady state.
