It shouldn't really be a surprise that scientists can be funny. A fair number of comedians come from a scientific or medical background, after all. Yet, on the whole, scientists have the image of being po-faced and incapable of getting a joke, perhaps because of a tendency to over-analyze. (Oops, I've started to analyze this. Stop me.)
One group in particular has tried to counter this image. It's a company called Biocompare which offers a comparison website that's not for insurance or electrical goods but for the kind of goodies life scientists (biologists to you and me) need. They have compiled a top ten of funny videos produced by the life sciences industry as a form of viral advertising (let's face it, if life scientists can't do viral ads, who can?) You can see all 10 here, but to get a flavour, here's one of my personal favourites.
