Bradley Walsh and Chase fans were left stunned and sickened tonight, when a contestant admitted what he did for a job.
Tonight's show featured Mark, 59, from Cheshire, but viewers at home couldn't believe Mark's profession.
Mark said he was a "Bovine Insemination expert" and explained to Bradley exactly what that meant.
He said: "I cover the length and breadth of the UK inseminating pedigree cows to make super cows.
"The cows don't mind it at all, I think they quite enjoy it."
Bradley asked Mark if he stayed in touch with any of the cows and Mark said: "I go back to see the same girls year after year."
And viewers at home found the whole thing hilarious, but also felt a tad queasy.
Paul Beeson said: "Trying to eat my tea god christ sake."
Gillian Hudson said: "Too much information!!"
Jas Judge said: "Hope he buys the cows dinner first."
Mr Chambers said: "As the cow said to mark ‘Is that a syringe in your pocket or are you just pleased to see me?’"
Mark had a good run in his cash builder before going up against The Vixen, Jenny Ryan, who was tonight's Chaser.
Jenny said: "You've got a very unusual job, but you'll excuse me if I don't shake your hand."
Mark said: "Yes you use your left hand to do the, you know."
Mark chose to take the middle offer, but he sadly went out of the competition after failing to get past the Chaser.
*The Chase continues at 5pm on ITV on Monday
