Flopped trips good kicker and Unknown pushes

[Kyriefurro]

Villain is a complete unknown. Haven't even played a full orbit against him.

0.50/1.00 NLHE 6-max, 6 players

Stacks:
Hero - $101.75
MP - $81.40

Hero is CO w/ K[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/diamond.gif[/img]

Preflop: UTG calls, MP calls, Hero <font color="red">raises to $6</font>, SB folds, BB folds, UTG folds, MP calls

($14.50) Flop <font color="blue">(2 players)</font>: 5[img]/images/graemlins/club.gif[/img], Q[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/club.gif[/img]
UTG bets $75.40 (all-in), Hero..........?

Obviously, he has a Q or 55. If he has a Q, I'm probably ahead since AQ would probably have raised pre-flop. If he has a 5, I'm drawing to 4 immediate outs plus 3 additional outs on thr river for the chance that the turn card will pair.

Ugh! What to do, what to do?
