QUIZ show fans are in for a treat this week with an ITV general knowledge legend appearing on Channel 4's Countdown.
Paul Sinha, aka The Sinnerman, has stopped many a quizzer from taking home a cash prize on ITV's The Chase, and this week the star appeared on a rival quiz show.
Countdown host Colin Murray welcomed Paul back onto the show as he took up a seat in Dictionary Corner alongside Susie Dent.
Colin wanted to try and outsmart the former British Quiz Champion guest and challenge him with questions he might not know.
Colin asked: "What country has the most pyramids?"
Paul replied: "Weirdly, I didn't know this until four days ago. It's not Egypt it's Sudan."

"Damn it! It is Sudan," an annoyed Colin said as he admitted defeat.
Numbers-whizz, Rachel Riley also joked with Paul about the greatest movie of all time, while she stunned viewers in a stylish floral dress.
Rachel questioned: "What is the top-rated movie on IMDb?"
Feel confident, Colin pipped up and added that he's got "no chance" of knowing the right answer.

Much to his dismay, Paul got it in one: "The Shawshank Redemption."
Rachel joked, saying: "No, actually, it's Sharknado 6," before she continued: "Of course it's Shawshank, yeah."
In another effort, Colin told Rachel to "lift her game, " prompting her to ask a question at singing sensation Cher.
Rachel started: "It came out that my best friend loves Cher from her hen do, so what's Cher's full name?"
Without skipping a beat, Paul replied: "I don't know if she has a middle name, but it's Cherilyn Sarkisian."
The studio audience applauded as Colin said, "That's amazing."
Countdown airs weekdays from 2:10pm on Channel 4.
