Biggest Donk Ever?

I sat with the biggest donk I have ever seen.  Good thing, too.  He was to my immediate left the whole day.  Let's run down what he did and how he donated.  

This guy was raising everything and because he was on my left, I didn't raise much.  So I limp with AKd and he raises and there is one caller preflop, the young guy to my right.  The flop comes 9d Ac 10d.  I check and the donk bets. Here is where it gets beautiful.  The guy to my right moves in thinking I checked with nada.  So he moves in and then I move in.  We each have around $161.  The donk now thinks for exactly 2 seconds and makes the call.!!  He immediately tables QhJh.  The turn and river are both diamonds and I take down the $550 pot.  Ahh, that's nice.

After this hand I sit for a while while this donk calls off $500 in a 3-way pot with a gutshot and hits, breaks 10 10 with A2 for $700.  Calls all ins with 93 and 62 and Q7.  It's unreal.  So this game is a 1/2 no-limit $200 max buyin.  At this point he is sitting with around $2200.  Seriously.  

I have a game plan and that is to continue playing very slowly letting him build pots.  This plan works to perfection.

I find Jh Jd and limp.  The donk is like clockwork and raises to $16 (in a 1/2 game!).  I make the call and hit the beauty, the Js.  The flop is 9d Js 6d.  I check the flop and he bets out $35.  I push in 20 red chips, making it $100.  He easily and without hesitation follows me into the pot.  The turn is the Qc.  It's a possible scare card but nothing too crazy to be concerned about with this guy capable of having 56o in this spot.  I bet out $100 again.  He calls again.  The river is a meaningless 4s.  I bet $100 AGAIN.  Now he goes into the tank, thinks for a minute, mumbles something about the 9, and then shoves it all in.  I have about $230 left and make the immediate call.  He confidently tables what he thinks could be the winner...7s 9c... a pair of 9s.  I show the set and take down $1100.  The plan works to perfection. 

Shortly after this hand the young guy who lost to me in the AdKd pot takes the donk for another $600 when he flops a set of 2s.  And shortly after that the donk was broke and left the table.  All in a days work.  +920
