I call.  Really?  Is he betting so big with AK or a set or overpair?  I totally disagree with his line - it does not make sense AT ALL, especially given his aggro PF nature.

Turn: ($57.00) Kh (2 players)
SB bets $26, Hero raises to $41.25 all in, SB requests TIME, SB calls $15.25
A turned King makes it far less likely that he holds a King himself.  The WTF part is why he's calling my re-raise shove; what can he possibly beat to warrant a call?  WTF?!?!??!

River: ($139.50) 8c (2 players - 1 is all in)

Final Pot: $139.50
SB shows 8s Qc (two pair, Kings and Eights) - LOL calling the turn with a Q as your equity; 3 outs once!  Did you really think I'm shoving Q7 or worse?  Oh yeah!  I could have 2 4 and been drawing.
Hero shows Tc Th (two pair, Kings and Tens)
Hero wins $136.50
(Rake: $3.00)
