Vladimir Putin, Donald Trump, and Angela Merkel are standing at the shore and are trying to impress each other with the accomplishments of their countries. Putin brags, "We have nuclear submarines which can stay underwater for six weeks without having to resurface!". Trump goes on, "Six weeks? That's nothing. I have the best submarines, they're underwater für at least three months!". Merkel is about to respond, when a giant steel colossus emerges from the sea. A hatch opens, a black uniform appears - "Heil Hitler! We need Diesel."
Me: Knock, knock.
Another person (OP): OP: Who's there? Me: Hatch. OP: Hatch who? Me: Bless you =) OP: But I didn't sneeze. Me: You just don't get a joke, do you?
