Two Polish guys are sitting on a park bench when a bum comes up to them.

"Hey!!" he bellows, in his hoarse voice. "I got a riddle for you two. What has two heads, four arms, four legs, and stinks like shit?"

The Polish guys look at each other, and one of them shrugs "I give up, what has two heads, four arms, four legs, and stinks like shit?"

"You and your friend!!" the bum staggers away chuckling.

The Polish guys look at each other and start laughing. "That was a funny riddle that bum told us" they say "let's go do it on someone".

Laughing almost hysterically, they see two American guys. They walk up to them and smile.

"Hey guys!" they laugh. "We got a riddle for you! What has two heads, four arms, four legs, and stinks like shit?"

The American guy's shrug, waiting for the answer.

The Polish guys chuckle again, and one of them says as he smirks "Me and my friend!!"
