Wil Wheaton was Cast After Posting a Tweet

Wil Wheaton tweeted about how much he loved the show and Steven Molaro, a writer on “The Big Bang Theory,” responded and invited him to a taping. A few days later, Bill Prady’s assistant sent him an email about appearing on the show. The writers wanted to create a nemesis for Sheldon, and Wil Wheaton couldn’t resist the offer.
