A guy worked for 30 years at the same factory. He got off work at 3:30, and was home by 3:45 every day of his life. On Fridays, he came home and gave his wife his check.
One Friday he was walking towards his car, and one of his co-workers asked if he wanted to go out for a beer. He'd never been asked before, so he said, "Sure, why not?"
One beer lead to another and that led to his first wild night out with the boys. Finally about 3:00 am he comes staggering thru the door. His wife is waiting for him and asks, "Where have you been?"
"Well," he said, "I went out with the boys for a few beers."
"You did, did you?" his wife fumed, "Well, just how much money did you spend?"
"As a matter of fact, I spent about $100.00," he said.
"$100?? Do you know how long that would last me?" the wife yelled.
"Well, " he said, "you don't drink, you don't smoke and you've got your own pussy... I guess it could last you forever."
