I Can Watch the Same Movie Over and Over

The Rocky Horror Picture Show. I don't know what it is about it that keeps it from getting old. I know not only every lyric and line, but also just about every callback and variation of every callback, And I've watched with director commentary on many occasions. I could attend a viewing blind-folded and with earplugs and point out with great precision when Columbus's nip slips out of her corset.
