Stinky

Got a call yesterday and this was how the conversation went:
Caller: Hi mummy.. it's E.....
Mummy: Who?
Caller: It's me, Stinky
Mummy: *laughing*

And then I'd forgotten why you had called me. I'm sure it's to tell me about something which happened in school. You are so funny, my little Stinky-Poo.
