I can't find the exact quote or the comedian who said it, but there's a great line about how a guy should be in bed that goes something like, "I figure if I can get the girl to sing the Star Trek theme, I'm doing my job." Well, here's a guy doing it down at the pub - singing the theme, that is.
Then there's this mashup of ST visuals to the Jefferson Airplane song "White Rabbit." Really quite brilliant.
And now for something completely juvenile.
