Silly Question of the Day

I am perusing my father's CD collection while driving his car to the beach yesterday and stumbled upon a CD that I would never have guessed my Dad would buy: Louis Prima. This is the man that introduced me to Led Zeppelin and had the Woodstock album. Luckily, a CD I expected to find was there as well: The USC Fight Songs (my entire family is insanely devoted to the USC Trojans).

So my question is, what unexpected CDs have you found among your parents collection? Which predictable ones were there, that gave you comfort?
