Hand the spec the cards, saying "Great! Show us another". Or "Wow, you really (cough "think you") know your stuff. Ok, here's another deck of cards. You do as I do"...
Or a simple comment like "Man, I bet you were the kid who blew out the candles on OTHER kids cakes, weren't you?"
Anything that will make other people think that it was pretty crappy to just spill the technique, should sort him out...
Trick is not to be too harsh, make the spec look like the bad guy. Don't get personal, don't be overly rude. It's all absolute key to saving face, and making him (or indeed, her) look childish. ALWAYS laugh it off, do not act like it's a big deal. If they don't look like they're gonna quit it, apologise to the rest of your audience and let them know they can catch up with you later...
