I must warn teachers not to approach this book. It's basically a collection of the most god-awful Christmas cracker/ ice-lolly-stick jokes you've ever heard, arranged according to grammatical type and with key grammar words (e.g. modal verbs) missing.
I seems that this could only provoke one of two reactions from students:
1) They fail to understand the puns, meaning you have to explain them. It hardly needs to be said that your lesson will be in deep trouble if this goes on too long e.g. if more than one is attempted
2) They get the jokes, and regard you with deep, silent contempt, possibly veiled by fake titters from the more polite.
Of course, a third option is always possible- that 'Grammar with Laughter' could result in hearty mirth, belly laughs and the slapping of thighs. But would you really want to be teaching such a class?
