A man walks up to the bar with an emu behind him.

As he sits down, the bartender comes over and asks for their order.

The man says, "I'll have a beer." 

He turns to the emu and asks, "What's yours?" 

"I'll have a beer too," says the emu. 

The bartender pours the beer and says, "That will be $3.40 please." 

The man reaches into his pocket and pulls out the exact change for payment.

The next day, the man and the emu come in again,

and the man says, "I'll have a beer," and the emu says, "I'll have the same." 

Once again the man reaches into his pocket and pays with the exact change.

This becomes 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 emu. 

"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?" he asks.

"Well," says the man,

"Several years ago I was cleaning the attic and found an old lamp. 

When I rubbed it a Genie appeared and offered me two wishes. 

My first wish was that if I ever had to pay for anything, I just put my hand in my pocket, and the right amount of money will always 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.

The bartender asks, "One other thing, sir, what's with the emu?"

The man replies, "My second wish was for a chick with long legs..."

Is he lucky he didn't get a cassowary instead?

How about the second wish is "enough space"?
