You may recognise Mark Labbett as the man who goes by 'The Beast' on ITV game show The Chase, who's been a popular fixture of the programme since 2009 and has since appeared in US and Aussie spin-offs.
You may have also taken his nickname at face value - he's the owner of a towering 6'6" frame, after all, and regularly makes the show's guests feel small with his Oxford-educated megabrain.
But one fan thinks there's more to it than just a beastly appearance:
The tweet said: "Only just realised that The Beast is called that on #TheChase because in French beast is la bête and his last name is labbett. Though they called him The Beast cause he's a fat c***."
La bête. Labbett. La bête. Labbett. See? Must be nice to have such a continental nickname - most people just get things like 'Jonesey' or 'dickhead'.
Mind you, that's not to say that the he doesn't also have a pretty beastly frame, often seen dwarfing host Bradley Walsh with his impressive height.
However, Mark recently revealed that his size has been the subject of a pretty unwelcome health diagnoses - having now been told that he has diabetes.
Speaking on Loose Women, he said: "Those who've got diabetes know there's actually several indicators.
"They check for cholesterol, blood sugar, weight is one of them. And my indicators are all quite comfortably in the yellow zone with one big one in the red zone: my BMI."
He also explained that the diagnosis has prompted him to make some changes, adding: "In some sense it made it easier, just no arguments now. I've enjoyed being this heavy, I always used to say I've got away with it. Well, now I haven't so the weight's coming off."
Another star of the show with an equally memorable nickname is 'The Governess', who's well-known for her trademark grey suit, white shirt with bow tie, red lipstick and scoffed expression, slaying contestants day in, day out, with little emotion.
But it turns out she looks far less intimidating in real life, where she's actually known as the not-so-intimidating Anne Hegerty.
Anne also appeared on ITV's Loose Women to talk about life behind that mask of 'The Governess', and viewers were shocked and surprised when the 59-year-old walked onto the stage in a flowing, bright top, make-up and flowery earrings.
Anne told the panel: "You can't imagine how much I don't miss the suit. I don't know if I'd say I hate it. I love doing The Chase, it's been fantastic, I hope it goes on being fantastic. But that is not what I'd have chosen to wear."
She also revealed that 'The Governess' wasn't the first title that the programme would bestow on her: "Originally, I was going to be called The Headmistress and during rehearsals Brad kept saying The Governess instead. I asked if I could change it to that - it's more kinky.
"A headteacher has a board of governors and OFSTED. A governess is a free agent."
