A team of scientist educators was trying to teach (you'll excuse the expression) monkeys to pull a certain chain to set off a bomb (a Pentagon project). Sooo...being brilliant fellas, they put a suitable concrete plug attached to an identical chain in the behind of an elephant. The scientists fed the elephant for six months a diet of curried cabbage, peanut butter, and other flatulogenic materials. They then hanged a bunch of ripe bananas from the chain with one tethered strongly.
They then released the monkeys. They recorded the entire event from bunkers at 1 mile, 5 miles and 25 miles from the elephant.
The bunker at one and five miles were obliterated, but the scientist in the bunker at 25 miles survived the tidal wave of...crap, and the white hot ball of gas. After beng dug out and rescued, the bloke was laughing insanely, and had to be carted off to the looney bin. Two years later, his laughing had died down to a cackle and chuckle. His doctor asked him, "After the death of the elephant and 50 monkeys as well as the deaths of your group of researchers just what did you find so laughable?"
After wiping his eyes, and stifiling yet another burst of laughter he repled, "Well, after we set the monkeys loose, they all scattered except for three...they climbed up the ladder to the bananas we hung from the chain and tried to pull them off as we trained them to do." He started chuckling and snorting again, but the doctor interrupted, "So? What was so bloody funny?"
The scientist said, "When the cork came out, you should have seen the expression on the monkey's face!".
