When "Fameless" returns to truTV for its midseason premiere Jaleel White of "Family Matters" fame pranks an unsuspecting wannabe TV star with the show "Are You Smarter Than a Primate?"

In Zap2it's exclusive sneak peek, contestant Ricky is pranked into believing that Koko the gorilla is so mad that he starts attacking host Jaleel White and his handlers -- and Koko isn't even real.

Ricky doesn't catch right away, even when the show tells him he's on a prank show. Oh, Ricky.

"You got me, David Spade!" Ricky says to the camera, referring to "Fameless" producer, comedian David Spade.

Also on the episode are a wannabe TV star finds himself trapped inside a mental institution, and a "cop for a day" sends a troubled stranger over the edge.

In the second of the back-to-back episodes, Jamie-Lynn Sigler guest stars as wedding bells ring for the wrong girl, and a self-proclaimed genius looking to bait crooks winds up taking the bait himself.

"Fameless" returns Monday, Jan. 18 at 10 p.m. ET/PT on truTV.
