A guy walks into a bar with an ostrich and a cat and orders a pint of beer, an orange juice for the ostrich and a glass of milk for the cat.
The ostrich smiles but the cat looks at him hard and says "Don't think I'm paying for these drinks, because I'm not." The guy says, "Don't worry about it, I'm paying."
They sit down in silence and drink. Then the guy walks up to the bar again and orders another pint, another orange juice and another glass of milk. The ostrich looks grateful but the cat stands up and shouts across to him, "I'm not paying for this round either." Wearily, the guy replies, "It's ok, this one's on me."
They sit in silence again and drink their drinks. Then the guy gets up again, goes to the bar and orders another round.
"Don't expect me to pay," shouts the cat. The guy just waves at him and pulls out his wallet.
"I don't mean to pry," says the bartender, "But what's with the ostrich and the cat?"
The guy looks at him. "It's like this," he says. "I was browsing at my local antique fair a couple of weeks ago and I saw this old-fashioned lamp. It was a bit dirty, but I liked the look of it, and it was cheap, so I bought it. When I got it home, I decided to clean it up a bit and, while I was rubbing it, this genie appeared and told me I could have one wish. I thought long and hard and then it came to me.
I asked him for a big bird with a tight pussy."
