Nice little clip. One of the links for videos from that is for a Canadian show called Corner Gas. Entitled Corner Gas rib tickle.wmv, it's a blond cashier played by Jane Robertson tickled by a male coworker while trapped under a deck, looking for something. He's egged on by the diner owner who suggests he search for coins between her ribs. She threatens him the falls into hysterics as he tickles and taunts her for several seconds. The other lady even tosses an eyeliner pencil down to try that later, but then the scene cuts out with the blond desperately struggling to escape. Nice scene, several seconds of action.
