One day, a man walks into a bar with an ostrich and a cat. The man orders a beer, and so does the ostrich. The cat orders half a pint, and refuses to tip the bartender. The bartender tells them their bill is $10.78. The man reaches into his pocket and gets exactly $10.78.
The next day, the man, the ostrich and the cat go back to the bar. They order the same thing as the day before, and again the cat is really rude to the bartender and won't tip him. The bartender tells them that their bill is $10.78. The man reaches into his pocket and gets exactly $10.78.
The next day, the man, the ostrich and the cat go back into the bar. This time the man and the ostrich order a double scotch. The cat orders a scotch and is rude to the bartender. The bartender smiles to himself, knowing that there is no chance the man will get the exact amount of money, and he's getting pissed at the cheapskate cat.
He tells the man that their bill is $15.63. The man reaches into his pocket and gets the exact change! The bartender is astonished. He asks the man how he always gets the right amount of change.
The man tells him, "Well, one day I came across a lamp. I rubbed it and a genie came out. He told me I could have any three wishes I wanted. My first wish was that I could reach into my pocket and get the exact change of anything I was buying."
"Very smart," said the bartender.
"My second wish was to have a high tolerance for alcohol."
"Good choice!" the bartender exclaimed. "What was your third wish?"
"Well, that wasn't too bright on my part. I wished for a chick with long legs and a tight pussy."
