During last night’s Saturday Night Live, hosted by Fifty Shades Of Grey star Dakota Johnson, the show paid tribute to the late Star Trek actor Leonard Nimoy, who passed away on Friday.

In a sketch titled “Emergency Room,” Kenan Thompson pays a doctor who gets called into work straight from a Trek convention dressed as Worf, the Klingon security chief from Star Trek: The Next Generation. At the end of the skit, Dr. Worf gives the Vulcan salute — the signal made famous by Nimoy’s Mr. Spock — before the screen showed an image of Nimoy in the original series giving the salute. (While Nimoy was known as part of the original Star Trek series, he did have a notable guest-star spot on TNG.)
