An undertaker from Failsworth in Greater Manchester has kept a chocolate bar at the bottom of his biscuit tin for 30 years.
Ian Kay bought the Marathon bar as a memento, back when Mars announced they would be changing the name to Snickers in 1990.
He preferred the name Marathon so thought he'd buy the original version of the nougat filled treat before it was too late.
Ian jokes it will probably stay in the tin 'until it evaporates into dust'. Failing that it might 'end up in a museum'.
He still lives in the same house he was in where he bought the caramel snack - the only thing that has changed is the biscuit tin it's kept in.
Mars recently announced they would be selling a 'retro edition' of the Marathon bar for a limited period. Ian, who's 56, said he'll probably buy a packet to put in the tin alongside the relic.
But he's got no intention of chucking out his old one.
Ian has no idea where he bought the Marathon bar from, and can't remember anything about the day in question.
Before he knew it, he'd kept it for almost 30 years.
And, he says, he's never been tempted to keep it anywhere else, or open the packet.
It's never melted, and if he moves it, then it might make it worse.
But, he says his wife Sharron 'isn't bothered' that he's kept hold of the Marathon bar. He doesn't take the chocolate bar out to inspect it, as he's 'not that sad', he laughs.
Ian says Snickers - or Marathons depending on your age - is 'up there' with his favourite chocolate bars, probably second to a Mars bar.
