After an awkward and less than ideal first impression during the CBS hit's fifth season, Hawking returns to the Thursday comedy this week where his friendship with the neurotic Sheldon (Jim Parsons) is threatened when a game of Words With Friends gets a little too competitive.

In a clip from "The Extract Obliteration" exclusive to The Hollywood Reporter, Sheldon's not only impresses himself (naturally!) with his prowess against the theoretical physicist and cosmologist but also gets Amy (Mayim Bialik) going as well -- for completely different reasons.
