Getting a fold from a fish

A few sessions ago, I had the pleasure of sitting down with a complete and utter fish.  This fish was the type that had no idea about the strength of hands, no idea about anything.  One thing he did understand is raising and being aggressive.  He loved to splash money in the pot, which was interesting because he didn't have a lot of money.

The table was a new table, but it was evident from the start that this guy had no idea what he was doing.  He'd be all in on a bottom pair, betting and raising like he flopped the nuts.  Inevitably, with these kinds of players, he would suck out to the best hand and amass a small but formidable stack.  It was like watching a roller coaster, though.  His raises were sickly - $20 with Q2, $30 with T8.  No rhyme  or reason seemed to apply - some people just like to watch the world burn, I guess.

Anyway, the roller coaster comes abruptly to a stop when he gets looked up by a second pair which finally holds, and he busts.  He gets up and asks about rebuys.  I smartly tell him they can hold the seat for him as long as he'd like - he was ready to leave and not come back.  Upon hearing that, he raced over to the ATM and was back 20 minutes later.

He sits down and within 5 minutes, his $100 rebuy is up to around $120 when he raises like $20 into me (I'm on his left, thankfully, but can't hit a freaking hand that plays well against his any two cards).  I have 8 8 and I consider 3betting, but feel like I can get it in on kind flop just the same as if I got it in pre flop - he's shown that he can fold 3bets and I don't really want him folding his BS cards.  Therefore, I just call and the table folds.

We see a flop of 3 7 7 and he bets into me - like $20 again.  This is a great flop for me.  This is so far ahead of his range, but he calls off stacks with Q6, etc. so I have no problem raising here.  Therefore, I raise to $60 and he just calls.

Turn is a blank and he checks.  I shove for $100 (he has $40 or so behind) and he tanks and tanks...  He starts talking about how he thinks I have a 7 and have him beat, which raises my eyebrows...  I need trips to beat him?  WTF?  Then he asks me if he folds, will I show him my cards?  I think this is a genuine question, not a probe for information, and I like the guy, so I agree - I ask if he'll show his cards which he quickly agrees.

He declares a fold and drops 33 for the flopped boat.  I show my 8 8 and scoop.  The table quietly stifles a gasp and an uneasy laugh as I scoop the pot for his perceived bluff.  He busts out 5 hands later and says his farewells to the table (I think they cleaned him out completely).  WTF?  I get the one friggin time the LAGtard has an actual hand!!!  DAMNIT!!!  But WOW!!!!

As we (the table) discussed the hand afterwards, we tried to piece together his thought process (which was admittedly a difficult thing to do).  The common thought was that he didn't understand poker hands, and thought he just had trip 3's, not a full house.  He thought if I held a 7, I had him beat with higher trips.
