Muck this OESFD to massive 200BB overbet on the flop?

[Logik]

$25NL at Pokerstars, six-max.

One limper, I'm on the button with 7[img]/images/graemlins/diamond.gif[/img] 7[img]/images/graemlins/heart.gif[/img] and raise to $1.00. SB and BB fold, the limper calls. Pot is now $2.35.

Flop comes:
6[img]/images/graemlins/diamond.gif[/img] 5[img]/images/graemlins/diamond.gif[/img] 8[img]/images/graemlins/diamond.gif[/img]

Limper pushes all in. His stack is $49 and my stack is about $55. Limper has been mixing up his game, and I caught him in a river PSB bluff earlier when I had top two.

Is it a profitable call?
