In "The Russian Rocket Reaction," Brent Spiner attended a party hosted by fellow Star Trek actor Wil Wheaton. At the party, he became a mortal enemy of Sheldon after breaking the seal and opening a signed, mint-condition, limited-edition Wesley Crusher action figure. Though he offered autographed Data dolls as compensation, Sheldon did not forgive him. However, Leonard and Raj attempted to take advantage of Brent's offer and, after some negotiating by Brent Spiner, both will receive the collectibles for $30 with the condition that Mr. Data will attend Leonard's birthday party. Sheldon portrays Mr. Data in "The Bakersfield Expedition" even though he is one of his mortal enemies.
