IN WHAT WAY IS IT DERANGED?
Dr Kataria advocates laughing as a form of cardio-vascular exercise and a means of reducing stress. He’s broken the giggles into various highly scientific categories, including “Visa-bill laughter” (wherein you presumably laugh because if you didn’t, you’d cry) and “swinging laughter” (which involves movements similar to The Hokey Cokey, and is not the victorious guffaw a randy man emits at a wife-swapping party).

PEAK OF THE FREAKINESS
The “milkshake laughter” at 1:36 – guaranteed to drive all the boys as far away from the yard as they can get – and the “ants-in-your-pants laughter” at 8:45.

IS IT A WORKOUT YOU’D ACTUALLY DO?
Well if the video makes you laugh, you sort of already are doing the workout, so… Well played, Dr Kataria. Well played indeed.
