The Chase Celebrity Special saw rugby star Ugo Monye face chaser Anne Hegerty in a general knowledge battle to raise money for charity.
And Ugo also managed to take cocky host Bradley Walsh down a peg or two when he made a savage jibe about the presenter's height.
Playing alongside other celebs including Mariella Frostrup, John Sargeant and Ranvir Singh, Ugo also revealed he has a tattoo on his backside and he does not even know what it says.
The question was: "Which of these is a hotel on the Las Vegas Strip?"
Ugo answered A) Mandalay Bay, and revealed: "I've been nine times and I've got a tattoo, me and a few of the lads got a tattoo."
"What does it say?" asked Bradley.
"I couldn't say, I genuinely couldn't say, it's on my backside, my mum has just found out which is nice, it will live with me forever now which is not a great thing," said Ugo, as the audience were in hysterics.
Later on, the question was: "What classification of planet did the International Astronomical Union introduce in 2006?"
Guessing "dwarf planet", Ugo explained: "I just heard Ranvir talking about you being small, and I had that in my head."
Bradley feigned fury as the audience cheered and whooped.
And viewers were crazy about Ugo and his one-liners, with one tweeting: "I would certainly be chasing Ugo #thechase #itv ".
" #UgoMonye on #TheChase Chase me lol" joked another.
Another tweeted him directly saying: " @ugomonye Just watching you on The Chase. That must be on hell of a tattoo of Mandalay Bay hotel on your a**e."
* The Chase airs on weekdays on ITV at 5pm
