"A Wish Comes True" joke

A man walks up to the bar with an ostrich behind him, and as he sits, the bartender asks for their order.
The man says, "I'll have a beer" and turns to the ostrich. "What's yours?" "I'll have a beer too" says the ostrich. The bartender pours the beer and says "That will be $
3.40 please," and the man reaches into his pocket and pays with the exact change for payment.
The next day, the man and the ostrich come again, and the man says "I'll have a beer," and the ostrich says "I'll have the same." Once again the man reaches into his pocket and pays with exact change.
This became a routine until late one evening, the two enter again. "The usual?" asks the bartender."Well, it's close to last call, so I'll have a large Scotch" says the man. "Same for me" says the ostrich. "That will be $
7.20" says the bartender. Once again the man pulls exact change out of his pocket and places it on the bar.
The bartender can't hold back his curiosity any longer. "Excuse me, sir. How do you manage to always come up with the exact change out of your pocket every time?"
"Well," says the man, "several years ago I was cleaning the attic and I found this old lamp. When I rubbed it a Genie appeared and offered me two wishes. My first wish was that if I ever needed to pay for anything, I just put my hand in my pocket and the right amount of money will be there."
"That's brilliant!" says the bartender. "Most people would wish for a million dollars or something, but you'll always be as rich as you want for as long as you live!"
"That's right! Whether it's a gallon of milk, or a Rolls Royce, the exact money is always there," says the man. "That's fantastic!" says the bartender. "You are a genius!... Oh, one other thing sir, what's with the ostrich?"
The man replies, "Oh, my second wish was for a chick with long legs."
