Smile, you might be on TV! What may be TV's first reality show is back to catch people doing unusual things on film without knowing it. Hidden-camera show "Candid Camera" first hit the air in the 1940s, and versions of the show have played in every decade since. This 2010 entry in the franchise sticks to the formula: Camera crews head to towns across the country to pull pranks -- sometimes with assists from celebrities -- on unsuspecting folks, then surprising them with the iconic phrase, "Smile! You're on `Candid Camera.' " Peter Funt -- son of series' creator and host Allen Funt -- co-hosts with actress Mayim Bialik.
