This Is My House returned for another instalment on Friday evening, with a panel of celebrities attempting to work out which one of four people was the true owner of a 17th-century hunting lodge in Shotts, just outside Glasgow.
The description for the show states: "Fake yourself at home.
"Four people, three fibbers, one house.
"Can the celebrity sleuths nose around and figure out the real owner?"
The episode saw Joel Dommett, Judi Love, Richard Madeley, and Sindhu Vee guess which of the four eccentric men named Erwin claiming to own the home was the real McCoy.

Each 'Erwin' had to try and convince the celebs how they came to own such unusual features such as a variety of farmyard animals, exotic glass items, and a waterbed in the bedroom.
In the end, the true Erwin revealed himself, but not before viewers on Twitter shared their thoughts.
One said: "I’m not sure I actually want to know who the real Erwin is."
"I would not enjoy visiting this house," joked a second.
"The Erwins really push the belief of each to their own to the very limit," argued a third.
Meanwhile, one unhappy viewer tweeted: "No, you’re not 'eccentric'.
"You’re not a 'character'.
"You’re not 'unconventional'.
"You’re a bunch of pretentious b******s whose lives have been lived a thousand times over.
"Grow up."
Other Twitter users wrote that they recognised the real Erwin before from a different reality TV show, and therefore knew his true identity.
One tweeted: "Watching #ThisIsMyHouse and I already know which Erwin is the owner.
"I remember him from #ComeDineWithMe . . . "
"Well that dude was on #comedinewithme," shared a second.
A third posted: "I know Erwin number two from somewhere and I can not for the life of me remember where but I feel like he is Erwin."
"He was on come dine with me, so I'm saying it's him," replied a fourth.
A fifth responded: "Shouted Come Dine With Me the minute he saw him!
"To be fair we started watching that series recently so he’s fresh in our memory!"
"Well that was easy to guess he’s been on come dine with me," argued a sixth.
