Bill Gates To Make 'Big Bang Theory' Cameo

CBS' "The Big Bang Theory" is adding another on-brand guest star. Microsoft co-founder Bill Gates has booked a one-episode appearance on the current 11th season of the geek-tastic comedy. Gates will play himself in a March episode during which Penny hosts him at work. And as you'd expect from "Big Bang," Sheldon, Leonard, Raj, and Howard do everything in their power to meet him. The episode will air later in March.
