Vampire #1: Mmm. Delicious. Vould you like some?
Vampire #2: no thanks. I couldn't drink another bite.
Vampire #1: So vat's new.
Vampire #2: Nothing much. I just saw a poor old bum begging on the street corner.
Vampire #1: You did. Vat did he say?
Vampire #2: He vanted me to help him. He said he hadn't had a bite in days.
Vampire #1: So what did you do?
Vampire #2: Vat else? Naturally, I bit him!
