Operation Ouch!

Identical twins Dr Chris and Dr Xand van Tulleken experiment and explore their way through the fascinating world of medicine and biology. The doctors show what really happens when people sneeze! Dr Chris gets his hands on a real human brain, and Dr Xand goes on call with an emergency ambulance team. Meanwhile, over in accident and emergency, one patient has a hook caught in their hand and another thinks he has lost a toenail up his nose.
