You wanted a puppy.
So we got you a puppy.
Then you wanted a bunny.
So we got you a bunny.
Then the bunny ate the puppy.
Now you want another puppy.
Moan moan moan.
Whine whine whine.
Complain complain complain.

(If someone can tell me where this came from, I'd be eternally grateful. All I know is I saw it somewhere.)
