Two familiar faces from Star Trek: The Next Generation will be appearing on The Big Bang Theory in an episode to air next month.
Both actors will appear as themselves on the episode, due to air on October 13.
On the episode, “Sheldon (Jim Parsons) makes Leonard (Johnny Galecki) choose, their friendship or a party at Wil Wheaton’s house. Tough one.” The CBS synopsis further adds that Wheaton is “Sheldon’s old nemesis.”
The Big Bang Theory, currently in its fifth season, airs Thursday nights at 8 PM on CBS.
