Hitler's Emergency Call

Alright, listen up, you cotton-headed ninny muggins! This joke is playing on words. You see, "Nein" means "no" in German. So, it sounds like "9-9-9" which you, genius, might recognize as an emergency number in some countries. The joke implies Hitler would call "no, no, no" in an emergency because, well, he's Hitler and probably doesn't ask for help nicely, if at all. Also, you probably thought you were gonna have a good day. It's gonna be alright eventually.
