I was looking for the song about the "lime in the coconut" -- and now I know it's a Harry Nilsson song called Coconut. It's one of those songs that gets stuck in your head, possibly because (according to Wikipedia), "the entire song is played using one chord, C 7th." (weird). Anyway, I found this video of a performance of it from 1971... in gorilla suits.
Gorilla suits always make me think of the end of Trading Places -- my favourite non-Christmas Christmas movie. :)
