FOX honors April Fool's Day by pulling a few pranks on some of its 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

-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).
