The last time he and Sam got legitimately wasted together was the night with cheap beer and Jack and that had started all of this. He'd said some things and made some moves and that had been that, and they'd been together ever since. He's down for getting wasted, but dancing? No.

"We're gonna get drunk," he counters. "Dude, dance with her. I'll do some more shots and watch you guys and, like, kick your ass if you get a boner dancing with my girl." And it's all for show, because Puck knows that Sam won't get one, and Sam knows that Puck isn't that stupid, and this is just continuing the charade. But, right now, he could use some more alcohol. And he needs to be away from Sam and the jealousy thing for a few minutes; he just can't deal with it, with the knowledge that he'll hurt one of them either way.
