Little rats

Chris: [looks very confused] What is that? [points at end of bed] (Sound familiar?)
Me: My hoodie.
C: Oh, ok.
M: What did you think it was?
C: A little rat.
M: A rat? Why would there be a rat in the bed?
C: I was waiting for you to tell me.
M: Where would it have come from?
C: I don't know.
