Does he always follow up the flop like that? Seems more like a maniac than an LAG (if he has something other than the other 2 aces or KK, thats just crazy).

I probably would have popped him back preflop...you would have had like 40% of his stack in the middle after doing so, and he'll probably commit the rest on most any flop. Playing it the way you did generates maximum fold equity on the turn, but I'm not sure if thats what you want if hes overplaying QQ-KK. He'll certainly be confused by your line, though, and if he folds now he may be more inclined to make a bad call later in the game when more is at stake.
