standard herd of morons with schnieds, bk, and i sitting next to eachother observing the animals in the zoo and dodging their poo flinging

UTG is the top of the top morons. Just sucks in general and plays his hands super wierd. Sometimes he raises with air, sometimes he waits to raise top pair until the river, sometimes he has quads. For what its worth, as i think its important in this hand, i watched him call the turn after spiking an ace (a8 on an 57JA5 board) on the turn then raise the river and pay off a three bet by the button who had quad 5's.

UTG raises, folds to hero in BB who 3 bets A [img]/images/graemlins/spade.gif[/img] Q [img]/images/graemlins/diamond.gif[/img], UTG calls

Flop: A [img]/images/graemlins/heart.gif[/img] 5 [img]/images/graemlins/spade.gif[/img] 8 [img]/images/graemlins/club.gif[/img]

I kinda want to hear thoughts on the hand before I share some of mine.. Thanks for the input in advance!
