Freshers' Fair ideas

It's not easy to come up with ideas for how to bring in the punters at Freshers' Fairs, or at least ones which aren't cheesy, cliched or expensive.

The CFTV blog is running a competition for funny ways of advertising CF at FFs.

It'd be good to hear of anything that has worked for you in the past as this is very much the preparation period for the looming Fairs (and I need more ideas for mine!).
