Star Trek‘s Leonard Nimoy will make a guest appearance on the CBS series The Big Bang Theory for its March 29 episode.

THR reports that Nimoy, who played the character of Spock in the original 1960′s Star Trek series and its subsequent movies, including JJ Abrams’ 2009 reboot, will voice the role of Spock during a dream sequence where he’ll speak to Sheldon, played by Jim Parsons.

On the series, Sheldon, the most obsessive of his group of young scientist geeks friends, is a big fan of Star Trek and Leonard Nimoy. One of the biggest moments on the show was when Sheldon’s neighbor Penny gifts him a napkin that was used then signed by Nimoy.

Trek and Spock are mentioned frequently throughout the series. In the episode The Lizard-Spock Expansion, Sheldon teaches his friends how to play a game he created called “Rock-Paper-Scissors-Lizard-Spock” (Sheldon explained the game again in a recent episode, this time to one of his rivals). One time, Sheldon ordered a cardboard cutout standee of Spock only to disappointingly discover that it was of Zachary Quinto’s Spock, not Leonard Nimoy’s.

Nimoy won’t be the first Trek alumnus to guest star on the show. George Takai appeared as himself in another character Howard’s dream sequence (along with Battlestar Galactica‘s Katee Sackhoff); LeVar Burton actually showed up to one of the gang’s parties; and Wil Wheaton has been in several episodes, as himself, as Sheldon’s nemesis.

The Big Bang Theory airs on CBS on Thursdays at 8pm.

他终于来了，相信大家对“潘妮送手帕”事件还记忆犹新吧，在第二季某集中，潘妮（Penny）用原版“史波克”扮演者伦纳德·尼莫伊（Leonard Nimoy）用过的餐巾换得了谢耳朵（Sheldon）的一个拥抱，这次他总算同意来客串了。

伦纳德·尼莫伊将出现在美国时间3月29日播出的新集中，然而他只会“现声”，在梦中以“史波克”的身份与谢耳朵对话。《生活大爆炸》执行制作史蒂夫·马拉罗（Steve Molaro）表示“这几年我们一直想请他来参与客串，圆谢耳朵一个梦，虽然这次他只是现声，但相信效果也会非常十足。”

《生活大爆炸》本周停播，最新集将于美国时间3月8日播出，播完后继续停播。按目前的播出安排，该剧于美国时间4月19日才会回归，但由于该新闻提到了3月29日的新集，播出安排也许会发生变动，提前到3月29日回归。此外《生活大爆炸》本季只剩6集新集，停播是为了能拖到5月份季终。
