If you're wishing you were at the Edinburgh Festival right now, you might want to watch the video above - and think again.
Because as it shows, Edinburgh comedy isn't all glamour, fun and deep-fried haggis, you know. Oh no.
There was comedian Andrew Doyle, merrily performing his stand-up hour Whatever It Takes, when he found himself dealing with some increasingly chatty, and increasingly drunk, audience members. As you occasionally have to do, when you're a stand-up comic.
But the final straw? Well, you'll have to watch it to find out (warning: there are some rude words along the way).
Doyle acquits himself wonderfully, saying: "Sometimes you need a bit of theatricality.... Telling jokes is just boring. I think it's much better when you're physically assaulted."
A tip of the hat to you, Mr Doyle - you're a consummate professional.
