Scotty Lago thinks the woman who got down on her knees in Vancouver and simulated kissing his crotch -- the infamous photo that got him kicked out of Vancouver -- was a set-up, because she tried to do basically the same thing to Michael Phelps.

The bronze medal-winning snowboarder was super chatty on his way into "Jimmy Kimmel Live," claiming the chick who kissed his medal and then went South had also approached Michael Phelps and tried dragging him into a make-out session.

As for the Olympic Committee making him leave Vancouver before the closing ceremony -- Scotty says he's pissed.
