I always enjoyed his character of Spock.
By the way, he wrote and performed this song himself for the episode Plato's Stepchildren.
Take care, young ladies, and value your wine.
Be watchful of young men in their velvet prime.
Deeply they'll swallow from your finest kegs,
Then swiftly be gone, leaving bitter dregs.
Ahh-ah-ah-ah, bitter dregs.
With smiling words and tender touch,
Man offers little and asks for so much.
He loves in the breathless excitement of night,
Then leaves with your treasure in cold morning light.
Ahh-ah-ah-ah, in cold morning light
