George Takei
From Muppet Wiki
Takei, Beaker, and some penguins.
George Takei (b. 1937) is an actor best known as Hikaru Sulu on Star Trek. He made a "featured appearance" on Muppets Tonight Episode 211, regaling Beaker with a steady stream of Star Trek stories.
During the episode, Takei had a chance of becoming a naval captain, but then he met Captain Kangaroo, who was also on board. The Captain was the highest-ranking officer on the cruise ship, so he became "Acting Commodore Kangaroo", much to Takei's chagrin. Said Takei, "Mr. Beaker? Set ego to bruised."
