Human: Oh hi Muffin. You want pets?
Human pets Muffin.
Muffin walks away.
Muffin: That will be sufficient. I shouldn't think that I shall ever require anything more, from you or anyone else.
30 seconds later
Yes hello, I need precisely one more pet please.
Uh oh, it's Friday the 13th and you just saw a black cat!
