A guy and his manager go down to the docks. The manager is betting every docker he sees that his guy can make love to 100 women in a row, without pausing, and satisfy them all.
Bets are made, and they agree that they'll meet the next day. The next day, 100 women are lined up along the dock . The guy drops his pants and starts.
True to his word, he moves from one to the next, satisfying each one without pausing: 1.. 2.. 3.. on and on he goes: 49.. 50.. 51.. He slows down somewhat: 83.... 84.... 85.... but he is still moving from one to the next, and the women are still satisfied: 97............ 98............. 99.............
...and before he can get to the last woman, he has a heart attack and dies.
The manager scratches his head in puzzlement and says, "I don't understand it! It went perfectly well at practice this morning!"
