with Terry Nutkins, Nick Davies and Chris Packham
How high does a flea jump? What's the smelliest animal in the world? And what's the fastest bird in the world?
Terry arms himself with fleas and tape measure to answer the first question.
Nick subjects some studio volunteers to a lot of horrible smells to answer the second. And Chris uses a police radar gun to measure the speed of the world's fastest bird - and it's British!
