There was a party going on and these guys surrounded the trailer.

The guys up front knocked and the party stopped quiet.

Someone inside asked who it was.

The bounty hunter in the back shouted through an open window 'Hey I know those guys man, let'em in!'

The guy at the door through open the door and said "Come on in! Party's just starting!"

Wrong, the party was over.

They got their guy and left.
