Conversation with Ben

Ben: (Looking at a small plastic dinosaur - not Bobgreen) What kind of dinosaur is this?

Me: I'm not sure, give me a look. (Notices that it is tall with useless little arms) Is it a T Rex?

Ben: No, it's not a T-Rex.

Me: Why isn't it a T-Rex? It has little arms and lots of teeth.

Ben: Because we've been learning about dinosaurs at school and I'm sure T'Rex's aren't purple and yellow.

Well, quite.
