Wow, dad, you're cool!
He's making a rather large assumption there.
That's kinda where my mind went, too.
I'm...fine with that.

I can't really fault this guy. Compared to some other Christmas myths out there (Krampus, Yule Lads, Whipping Father, etc.) the Joker seems rather tame.

He does routinely drag children to hell. Does that count?
