Bradley Walsh was close to hysterics on The Chase on Friday night after he was faced with some rather interesting answers to a question.
While trying not to laugh, the host read out some very cheeky phrases to a question about plumbing terminology.
It was during the final round with quizmaster Mark Labbett, aka The Beast, where the 60-year-old had to stop himself from losing his composure.
Even one of the contestants, Scarlett, called Bradley out for being immature and jokingly told him to "behave".

"Which of these is not a common piece of plumbing terminology?" Bradley asked contestant Eddie, before reading out the three possible answers: "A) Blow bag, B) Fiddleback or C) Flange bushing."
Eddie said he "had heard of flange", which led to Bradley grinning and pulling a face towards the camera.
"You don't want to be going fiddleback while you've got the old flange bushing that's for sure." He then quipped.
"Bradley behave yourself," Scarlett tutted.
Many viewers watching the episode from home flocked to Twitter to react to the hilarious moment.
One viewer said: "I need to grow up but these answers made me giggle."
"Flange bushing" and now "Schwing!" Total smut on #TheChase today." Giggled another.
"Flange bushing from carry on chaser," joked a third.
"Three different people tweeted "flange bushing", accompanied with a gif of Kenneth Williams!" pointed out a fourth.
