Angry Grimace
Two cannibals are eating a clown. One turns to the other and says "does something taste funny to you?"
The part that got lost in all this is that Day's Undoing is actually a really interesting card for both Standard and Modern. Its a card that *could* absolutely be broken even though you're letting your opponent take the first crack at it if you're getting a significant enough card advantage, or even against control (because you force a mull on them)
