We all love a good laugh, but why do we do it? What is it exactly that makes our mouths curl up, eyes water and noses snort like a pig? Join Professor Ian Mclaughlin and special guest Doctor Daniel Watkins from the Institute of Comedy Research as they take us on a belly laugh ride through the current scientific theories about guffaws and giggles. But whatever you do, dont heckle, as theyll be looking for guinea pigs to test. Expect science, custard pies and live experiments.
