I've seen a couple dozen or more Mutt & Jeff cartoon and must say that "When Hell Freezes Over" is by far the strangest...and possibly the funniest.
When the story begins, Mutt & Jeff are both in two beds next to each other and they keep yanking the blanket off each other because it's so cold. Finally, they go out side to try to find something to burn...and soon they are captured by a demon and taken to Hell. There, they discover that it's also freezing cold there and the boys are given the task to try to warm it up. What's next....well, it's pretty weird and silly.
Clever, funny and very original....and well worth seeing.
