this guy is a complete lag

Preflop sure, but that doesn't mean he'll go crazy with nothing postflop. It all depends on how you've seen him play after the flop... If he's one of those bet, re-raise with nothing types, then sure, call. If he's not, or if you haven't seen anything, then standard fold.

Be sure to not be one of those guys who will call any bet with an overpair.
