She said, “Would you like to take a shower?
I’ll show you up to the door”
I said, “Oh, no! no!
I’ve been through this movie before”

from Bob Dylan – Motorpsycho Nightmare Lyrics on Rap Genius

Meaning

Rita shower’s invitation is less than appealing, considering that she looks like Anthony Perkins, the killer of Alfred Hitchcock’s famous shower scene in Psycho.
