KQo from early against a lagtard maniac

This one got me to shut it down for the night last night. Villain is Lagtard Maniac. Pops w/ T2o preflop and bets with nothing as an example. Occasionally shows up with a real hand. I went into call-down after he blasted at me on the flop. Talk to me, goose, this kind of player gives me the most trouble...
