What Are They Talking About?

I tried this game out the other day in a class of grade five and sixes. It was fun. There was a bit of groaning at the beginning, but that might have been more to do with my choice for the out of context sentence. Here is a sample conversation: A: Tomorrow is my birthday! Oh the phone is to ringing... B: Hello. This is the zoo. Would you like a free animal? A: Yes, I would! B: We have some lovely gorillas. A: Um...I'm not sure. B: We will send them to you today. A: I don't want any gorillas! (the out of context sentence I wrote on the board.)
