This truly is a one of a kind story!
When Maragret Rees died in 2013, she left her sons David and Gareth bit of inheritance money. They had spoken about what the two men should do with it, and it's not what every parent would recommend.
Margaret (or 'Olive' as she was known) wanted her boys to use the money wisely and travel the world supporting the Welsh team wherever they went.
They bring a little memento of their mum on their trips, so she's always there to help with the beer tokens.
Dermot and Dave gave David a ring to see how they're feeling about their trips to Dublin this weekend, and find out a bit more about this incredible tale.
David is an absolute champ, and Olive a legend too!!
