WPT Gold Strike WPO - What was with Scotty N.'s fake call/fold?

[otnemem]

Just watching it on Travel Channel. Gavin Smith limps in the SB with QQ. Scotty checks with 29 or something. Flop comes 2-x-x. Gavin bets. Scotty thinks for a while, stacks a few chips, throws a couple in, then tosses his cards in the muck and laughs. Mike Sexton comments on it, saying he was tossing in his small blind or something. I watched it two or three times but can't figure out what happened. Please help me feel less stupid. Thank you.
