A prankster planned to give his girlfriend the surprise of her life by lying in bed with her best friend.
But the stunt backfired - when she returned home with another man herself.
Chris Monroe, who runs YouTube channel PrankInvasion , enlisted the help of his partner Nicole's best friend for his latest wind-up.
The plan was that Nicole would find them in bed and be furious, but she was one step ahead of him.
Having been tipped off by her friend, Nicole roped in her friend's boyfriend to get her own back.
The pair enter the flat hand-in-hand - to shocked Chris's apparent anger.
He begins the trash the apartment before his lover bursts out laughing and he realises he has been had.
