What do you do?

Look him straight in the eyes and say "I love Jews" and then slap him across the face

Ask him to "pass the juice" and boom, you get your seat back

It depends on whether I had been transported to the 40's, Hitler had been transported to now, or Hitler's dead body was sitting at the table. All very different scenarios that demand different reactions.

B!tch slap him and tell him to go back to his own time

Tell him not to invade Russia in the winter and that the Allies are going to hit hard at Normandy.

I'd be fuhrious
