Don't be nasty. Use humour to highlight extreme policy positions taken by opponents. Humour does not happen by accident, so think seriously in advance about your strategy. Use friends wisely. Spend lots of time researching in the pub.
Nobody can invent good gags by order of a committee, so get the beers in.

You will be surprised what people will do for a laugh. Pick 'sneezers' carefully, and ensure they know how important their role is.
