'Big Bang Theory': Leonard Revisits His Tortured Youth (Exclusive Video)
On tonight's Big Bang Theory, Leonard (Johnny Galecki) takes a stroll down unhappy memory lane when he's visited by his old high school bully, Jimmy (The Comeback's Lance Barber).
In a clip exclusive to The Hollywood Reporter, Sheldon (Jim Parsons) attempts to help Leonard figure out just what Jimmy could possibly want -- by listing some of the ways in which he was tormented in high school as Penny (Kaley Cuoco) proposes a funny way in which the gang could spend New Year's Eve.
The Big Bang Theory's "The Speckerman Recurrence" airs tonight at 8 p.m. and returns from its holiday hiatus on Jan. 12.
