‘If you’re weak-stomached, hospital clowning may not be for you,’ warns a pink-shirted Peter Purves lookalike on a gurney who claims he’s ‘better known as’ Bubba the Clown – and so begins one of the most horrifying clips in the history of YouTube.

Whether or not being a clown at a hospital is an actual form of paid employment in the United States is unclear, but Bubba certainly takes it seriously enough.

‘You want to be funny, not obnoxious,’ he explains, before cautioning potential casualty ward entertainers against telling patients they’re going to get better. ‘It doesn’t necessarily be true,’ he says ungrammatically, now having added a white coat and THE WORST CLOWN MAKEUP IN THE WORLD to his get up. ‘They might be terminally ill.’
