to Adult Swim's Too Many Cooks:
I think we can all agree that this is not even a contest. Too Many Cooks is WAY funnier than HItler's painting.
It's pretty good realism for a Hitler painting, though he kinda gave up when he got to the sky and the trees (never stop reaching for the stars, Hitler!).
It's also a little too pastoral, and Too Many Cooks is definitely commenting upon such dull art. Had Hitler been around in the 1980's, he'd probably have really enjoyed some of the sitcoms that Too Many Cooks parodies (except The Cosby Show!). Honestly, I think he would've loved Bosom Buddies. Nothing makes an old German stuck-up idiot laugh harder than a man in woman's clothing.
He'd probably have been a huge Tom Hanks fan (up 'til Saving Private Ryan anyway.)
It goes without saying that Too Many Cooks has a much more appealing serial murderer in it, though they can't be rated based on appeal. What makes a serial killer valuable? Is it his ability to murder, or is it his style? If it's the former, Hitler wins (though very lazily!) If it's the latter, Too Many Cooks wins hands-down, with the funniest serial killer we've seen all year.
Too Many Cooks falls apart at the end, but it does start out funny enough that we have to rate this higher than anything we've covered so far.
4 mustaches
And for Hitler? One mustache
and one Smarf
How much is a Smarf worth in mustaches? Who cares, it's art, let it be subjective, or you're making the same mistake Hitler made! You wouldn't want to be compared to Hitler, would you?
