The Chase viewers couldn't believe their eyes today as they thought Mary from Gogglebox was on the show.
Armin, Sally, Karen, Ryan were all hoping to defeat Shaun Wallace and walk away with thousands of pounds.
The first two contestants, Armin and Sally, performed well under the pressure, with Armin securing £5000 and Sally adding £7000 to the prize pot.

But fans were stunned when they saw Karen.
Many viewers at home thought she was the spit of Mary from Gogglebox.
Mary and her husband Giles joined Gogglebox for the fifth series in 2015.
Giles is known for his philosophising, which often sees Mary trying to bring him back to reality.
The pair call each other 'nutty', but neither can remember why.
And with them being one of the more popular cast members, fans were delighted when they saw Mary's lookalike on The Chase.
Taking to Twitter, one wrote: "Next up is Mary from Gogglebox."
Samantha said: "Mary from Gogglebox Seat 3!"
A third added: "Oh nutty well done."
And a fourth said: "Really looks like Mary."
Karen, who was hoping to use the prize money for either a new bathroom or puppy, won a solid £5000 in her cash builder.
Unfortunately, in the final chase the team weren't able to compete against the intelligence of Shaun Wallace and missed out on £17,000.
