2 pair against a loose passive

[Daddy Warbucks]

Villain is 42/0/1.6 over ~200 hands. I've seen him overbet before, but it never went to showdown. At the time i thought his flop call looked suspicious, and it hit QJ, so i checked. He seems to play pretty weak tight.

If you were deeper, I would prob. call and c/f to a big river bet. I really can't see folding with his stack.

I don't mind b/f the turn though.
