Classic Star Trek fans rejoice! Leonard Nimoy will reprise his role as Mr. Spock on this Thursday’s episode of  The Big Bang Theory — but he won’t be playing the role by himself. Instead, Nimoy will lend his voice to an 8-inch, cloth costumed Mr. Spock figure from Diamond Select Toys’ Star Trek Retro Cloth action figure line! An exact replica of the classic 1970s Mego figure (faithfully executed for Diamond Select by the designers at EMCE Toys), Mr. Spock has a conversation with Sheldon Cooper (Jim Parsons) in a dream, and convinces Sheldon to open up a rare, mint-in-box Teleporter Playset (released in the U.K. by Palitoy in 1975).

For those of you looking to have your own personal conversation with Mr. Spock, the figure is sold out, but a Mirror Universe version of Spock will be available later this year in the Retro Cloth line, along with Mirror Kirk, Captain Picard and a Borg!
