Andy Milne has garnered a reputation as an England superfan and Three Lions supporters are just learning what he does outside of following the team.
Milne went viral for supporting England at the 2022 World Cup in Qatar, with some on social media claiming that he looked like former England manager Steve McLaren.
He has become a cult figure among fans after he was snapped in Qatar hoisting a replica of the Jules Rimet Trophy during England's 3-0 victory against Senegal.
Fans had also nicknamed him 'World Cup Guy' and was also pictured following England's Lionesses during their 2023 Women's World Cup campaign out in Australia.
Milne, a retired biology teacher, has been spotted in the crowd at multiple England matches at Euro 2024.

And fans have been surprised to find out what he gets up to outside of football.
Milne saw a gap in the market during a school trip to Thailand and decided to act on it.
He now runs a real-life treasure hunt in the country on an island that is part of the Chumphon Archipelago.
The website for the experience reads: 'Treasure Island Challenge is a unique six-hour fully immersive experience that will take you across the stunning island of Koh Tao on a quest to find its hidden treasure.
'In teams of no more than twelve, you’ll be led across Koh Tao on a full-day adventure.'
Participants will 'solve clues that will take you across the island, meet friendly locals to help you in your quest, visit charming beaches and secret coves and snorkel for clues amongst stunning marine life.'
You will also 'visit wonderful viewpoints where you can see the whole island' and 'sample delicious local food and drinks throughout the day.'
'When you arrive, you get to a pirates den, and then after the introduction, you begin. The start is like a traditional escape room,' Andy told The Mirror last year.
'Customers work out the clues to find their treasure map. Then they will set out in groups of up to 12 for the day.

'They will follow a route through the main town, visit local businesses to find their provisions and transports. The tour takes them to four beaches and view points. They get to snorkel for clues and follow a trail underwater to find a giant sea creature.'
When asked about his popularity with England fans at Euro 2024, Milne said: 'I think it's because my face keeps appearing on the telly. I've been to a lot of tournaments, this is my ninth Euros. I've been to eight World Cups and the Women's World Cup as well.'
He added: 'I've seen no trouble, I've had a fantastic time, here in Frankfurt it's glorious and the atmosphere in the fan park is unbelievable.'
