The Chase host Bradley Walsh is used to hearing a range of wrong answers on the show, and he does not usually lose his cool while reading out the questions.
But even he could not prevent a giggle from escaping when charming contestant Nicola guessed some real duds during her cash builder round.
Nicola seemed a little put off by the pressure of TV, understandably, and she missed some answers viewers felt were blindingly obvious.
Her worst mistake was likely guessing "Martin Kemp" on a question asking which Hollywood actor starred in Grosse Point Blank.
And when asked: "What is the usual term for the area served by a school?" Nicola guessed: "The playground?"
The answer was, of course, the catchment area, and some viewers were shocked a teacher would get it wrong.
On the question: "Taking the form of a jaguar, Tezcatilpoca was god of the night sky in what mythology?"
Nicola guessed: "Egyptian, because they worshipped cats and jaguar is a cat isn't it?"
Staring at her, Bradley said: "Where do you find a jaguar?"
Nicola replied: "The Amazon? Oh it's Aztec isn't it..." as the screen told her she had guessed incorrectly from the options Egyptian, Aztec and Polynesian.
After her cash builder, Nicola remarked: "I don’t really know what to say there..."
Bradley reassured her: "I do ,two grand - better than nought,that!"
One viewer tweeted:" #TheChase Bradley "What is the usual term for the area served by a school?" Nicola "Playground" Bradley "Catchment area" Nicola is a school teacher".
"Did she...I...I hope her students are watching this #thechase," joked another.
"Teacher on #TheChase unsure about term ‘catchment area’. Put it down to nerves :-)" wrote a third.
"That was absolutely DISASTROUS, even for a teacher! I mean, Martin Kemp?! #TheChase," ranted a fourth.
Nicola played against Jenny 'The Vixen' Ryan in the next round, but sadly got caught and was sent home empty-handed.
* The Chase airs weekdays on ITV at 5pm
