Several Star Trek stars, including Wil Wheaton, Brent Spiner and LeVar Burton, have appeared on The Big Bang Theory, and now it's Leonard Nimoy's turn.
Nimoy will reprise his role as Spock in an upcoming episode of the show, but only in Sheldon Cooper's dreams. Previously, the closest Sheldon has come to his Vulcan hero is owning a sample of Nimoy's saliva.
It's likely that Nimoy's appearances on Big Bang will be limited to dream sequences, though, because he's got a restraining order out against Sheldon. And, considering Sheldon's obsessive fanboyism, that seems like a highly logical move.
Nimoy's episode airs March 29th.
