An atheist World War II vet dies and goes to heaven where he meets God, showing off his existence in a moking display. God says, “bad news, friend. You know what the penalty for disbelief is, but I’ll tell you what, if you can make me laugh, I’ll let you in.”
The atheist thinks...”who was the best baker ever?”
“Who?” God says with an unamused face, of course already knowing the punchline.
“Hitler. He made 1 million Jews toast.”
...“That’s not funny,” God says.
The WWII vet shrugs his shoulders. “I guess you had to be there.”

I originally heard a version of this on reddit. Hope the toast joke isn’t too much.
