Dumbest Co-Op Bot?

Having fast-leveled an account (this one) entirely using bot matches, and played my fair share of them for FWOTD or trying out champs, I'm rather familiar with the tendencies of each bot and some are, let's be honest, kinda... touched in the head. Which, though, would get your vote for dumbest?

For me, it's Ryze... by far. He initiates with his ult as if it were his old ult, just teleporting random places with it. He'll do the bronziest of tower dives on you for no apparent reason. No matter how far behind he is, he'll try and all-in you. He could be one auto away from dying, but still walk right into your range for some stupid reason. He can't combo worth a damn. It's like picking on a mentally deficient pre-schooler.

Who else do you think is worthy of consideration for the award?
