A man walks into a bar, sits down and picks up a minature piano and puts it up on the table. He also opens his bag and a 30 cm tall man jumps out!

The bartender is really suprised, but gladly asks the man.
Where did you get that from?

The man answers; I got a lamp with a spirit in it that grants wishes

Bartender; May I try it? The man nods and gives him the lamp

I wish I had lots of money!

Suddenly, its started to rain bunnies outside!
Oh yeah, I forgot to mention, the spirit dosent hear too well. Otherwise I wouldnt wish myself a 30 cm pianist..
