The singer started sulking after Rizzle Kicks used Fun Lovin' Criminals lyrics in the 'Next Lines' round of the competition, a standard practice on the comedy music show.

Noticing that Morgan was unhappy, Rizzle Kicks asked: "Are you alright with that?"
Morgan replied: "I'm totally alright with that, I just thought you guys might do something different for a change."
The hip-hop duo reply: "It's part of the game Huey... It's next lines mate."
Growing increasingly frustrated, Morgan ends the game by smashing his mug on the desk, with pieces shattering across his desk near teammates Phill Jupitus and Laura Whitmore.
"Huey, it's the game bro, I say a line, you sing the other line. You don't have to smash a mug in my hair," laughs Jordan Stephens afterwards.
Morgan continued to grow restless as Rizzle Kicks joked about the incident and rival team captain Noel Fielding mocked the mug smashing incident. As the final shot of the episode was filmed, Morgan walked out of the studio, appearing to be annoyed with the presenters' behaviour.
Never Mind the Buzzcocks airs tonight (November 4) at 10pm on BBC Two.
