FOX honors April Fool's Day by pulling a few pranks on some of our very own television talent. Among the shenanigans are a culinary gag on fiery Hell's Kitchen chef Gordon Ramsay, a noisy interruption on the set of House, an unexpected visitor startles Dollhouse's Eliza Dushku, the cast of Terminator: The Sarah Connor Chronicles does an interview they won't forget and David Boreanaz and Emily Deschanel of Bones freak out their castmates.

Tune in tonight to catch the foolishness throughout the evening during commercial breaks in Lie to Me (8:00-9:00 PM ET/PT) and American Idol (9:00-10:00 PM ET/PT).
