On Monday's episode of The Big Bang Theory, "The Creepy Candy Coating Corollary," Wil Wheaton guest stars as himself. Sort of.

Unlike the real-life Star Trek actor (who's actually a nice guy), the actor will be portraying a version of himself that had an argument with Sheldon during an autograph signing years ago.

Now, Sheldon looks at Wheaton as his nemesis - and the two of them will engage in an epic card battle on Monday. Look for Sheldon to eam with Raj on his team, while Wheaton will partner with the comic book store owner, Stuart.

Check out an early look of Wil Wheaton on the sitcom:

Meanwhile, Wolowitz will spend the episode begging Penny to set him up with one of her friends.  Check out some more pics from the episode:
