What's hilarious about this video isn't the fact that it's a fat kid trying and failing to do a bike stunt. It's his reaction after his bike falls over and he comes skidding to a halt on the gravelly ground.
"I'm dying" he proclaims, "Help me." And that's enough to make you fall about laughing uncontrollably.
While we're on the subject of fat kids crashing their bikes, check out this chubby casualty below and try not to snigger.
And finally, if you haven't used up your schadenfreude for the day, here's another tubby tumbler eating stairs as he flies over the handlebars and no doubt instantly regrets whatever it was he was trying to do.
