While doing a show in Vancouver, Canada, the busker is precariously balanced on a skateboard, on top of a piece of piping, which in turn is on an unsteady looking platform.
During the clip, he is addressing the audience when out of the crowd a precocious youngster runs up and starts shaking the structure he is perched on - before running back off to his mother.
In no mood for the child's antics, as soon as he regains his balance the performer shouts: "F**ck man be a parent, hey?"
"Dude when I get down you'd better run.
"You're young, but you need to learn a lesson. That wasn't cool, yeah?"
The crowd seem to agree with him, cheering the performer on.
"Do you apologise?" he asks the boy, before saying sorry himself to the rest of the audience.
Then he drops the bombshell: "Some people should really use a condom."
