Whilst pondering the answer, Shaun accidentally timed out - forgetting to press his buzzer.
Shaun told host Bradley Walsh: "That's the first time in 10 years I've done that."
Sharing the clip on Facebook, The Chase's admin said: "Reminder that Shaun was one of the two original Chasers back in 2009 and has NEVER made this mistake before.
"Although John also got it wrong, but is this slip up a sign that Shaun is a little shaken?"
