Let me introduce Basil the Rat...
Manuel: I say to man in shop, "is rat". He say, "No, no, is special kind of hamster. Is Filigree Siberian hamster". Only one in shop. He make special price, only five pound.
Basil: (calmly) Have you ever heard of the bubonic plague, Manuel? It was very popular here at one time. A lot of pedigree hamsters came over on ships from Siberia... (he takes the cage)
Manuel: What are you doing?
Basil: I'm sorry, Manuel, this is a rat.
Manuel: No, no, is hamster.
Basil: Is not hamster. Hamsters are small and cuddly. Cuddle this, you'd never play the guitar again.
