Leonard Nimoy never actually appeared on The Big Bang Theory, but his persona always loomed large in the world of Sheldon Cooper.

To pay tribute to Nimoy, who died Feb. 27 at the age of 83, the show’s producers gave a shout-out to the Spock’ actor in the vanity card at the end of the episode.

The Nimoy episodes of TBBT are among the show’s most revered. The first time the CBS comedy revealed how much Sheldon (Jim Parsons) worshipped the Star Trek actor was in “The Bath Item Gift Hypothesis” from season 2. Penny (Kaley Cuoco) gives Sheldon a napkin that Nimoy used and autographed at her restaurant.

“I possess the DNA of Leonard Nimoy!” Sheldon exclaimed. “All I need is a healthy ovum and I can grow my own Leonard Nimoy.”

In the season 5 episode of “The Transporter Malfunction,” Nimoy provided voiceovers for a sequence in which a Spock doll starts to talk to Sheldon. Spock admonishes Sheldon for not playing with his Star Trek toy.

“You need to play with the transporter toy,” Nimoy said. “Remember like me you also have a human half.”

Nimoy died after a long battle with chronic obstructive pulmonary disease at his home in Bel Air.
