An all-day drinking session came to an embarrassing end for one Dundee man after his cheeky pal decided to finish his night with a bang.

Construction worker Craig Martin, 28, can be seen propping up the bar in the Nine Maidens pub in Laird Street as he chats up a barmaid after last orders.

Dressed in a red beanie hat and yellow high-vis jacket, the unlucky punter is blissfully unaware that his world is about to be turned upside down.

The hilarious footage shows his pal Mark Roberston, 32, creep up behind him, swiftly skanting him before hurling Martin and his naked undercarriage over the bar.

As the barmaid looks on, the unsuspecting victim takes an almost graceful tumble in all his glory, mooning the pub's CCTV camera in the process.

He has no clue what's his friend is about to unleash

After righting himself, he gives his practical joker pal a thumbs up before stoating away from the bar - unphased that he lost his hat in the excitement.

Prankster Mark Robertson said: "We were waiting for Craig to come out of the pub but he was taking ages.

"I don't know what possessed me to do it. It's fair to say he'd had a fair few drinks - we'd been in the pub since 3pm.

"He didn't hurt himself and finds it funny."

The pub manager , who is a friend of the pair, shared the side-splitting video in a group chat the next day.

The pair are still pals after the practical joke

But Robertson isn't afraid of the inevitable payback.

He said: "I'll have to watch my back but it'll be alright. I'll just have to see what happens."
