The Big Bang Theory is sure to make you tear up, thanks to an upcoming appearance from the late Leonard Nimoy's son.

Adam Nimoy will appear as himself in Big Bang Theory's Nov. 5 episode, sweetly titled "The Sock Resonance," with a special proposition for Sheldon (Jim Parsons), CBS announced Monday. Nimoy will be stopping by to ask Sheldon to take part in a documentary about the late Star Trek star.

The Star Trek legend never physically appeared on The Big Bang Theory, but has long played a part in Sheldon's story. Leonard Nimoy provided the voicework for an episode in which Sheldon dreams his Spock action-figure is talking to him, Sheldon has dressed like the famed Vulcan and of course is part of "Rock, Paper, Scissors, Lizard, Spock."

Nimoy passed away in February at the age of 83.

"The Spock Resonance" airs on the show's new day and time, Thursday, Nov. 5 at 8/7c on CBS.
