tumble dry

You know how something can be so dumb, that you really just don't know what to say about it? Well this is definitely one of those instances. According to the Daily Mail -

An investigation was underway today into a dangerous prank which saw a fireman being tumble-dried by laughing colleagues. A video of the incident shows the fireman climbing into a giant dryer having put clothes inside to protect himself from the heat. He then mouths to his colleagues, one of whom was filming it on his mobile phone, to let him out when he says so. Once the machine is switched on, others can be heard laughing at the firefighter spinning around in the dryer. The footage was passed on to bosses at Greater Manchester Fire and Rescue Service, who immediately launched an investigation into the incident.
