Conversation with Island Boy this evening...

Madame Chiang: So, what did you get up to this evening
Island Boy: Went to see 'Transformers', you should go see it, it's fun...
MC: Nope, that sort of thing doesn't interest me...about as fun as watching paint dry
IB: Oh, What's that about?
MC: ....Long pause....
IB:..Ohhhhhhh!!!!
