"Excuse me?" Skulduggery tilts his head, which is all he can do to properly convey his surprise at being called a liar. He'd literally done all of those without lying once!!! Except for that last part, but now that he's being called on it, he's decided that he was just joking. Of course he would uphold a bet like that. Who the hell does Max take him for? Some kind of cheat?

Wow! Offense taken.

"Well good to know you're the man of honor around here," he grouses. "For your information, I would wear that shirt, and I would wear it proudly. I'd tell everyone that it was my favorite shirt. I'd stand up on this table right here wearing it and proclaim it to the entire damn party!"

Okay, that's... a bit further than he's really willing to go, but it's out there now. It's out there on the table, right alongside that ugly goddamn shirt, and now his very fragile pride is wrapped up in it.
