Guy: Why can't Jesus have M&M's?
Priest: Why?
Guy: Because they'll fall through the hole in his hands.
Listen up, buttercup! This joke is about Jesus and the holes in his hands from being nailed to the cross. If he tried to hold M\&Ms, they'd just fall right through the holes! It's funny 'cause it's a silly image, and you are even sillier for not getting it.
