A GoFundMe page has been set up to buy a Leap card for Conor McGregor's da, Tony.
He's shared a bizzare video of himself giving out about getting €17.30 "in coinage" when buying a ticket for the DART at the weekend.
Tony says he used a 'crisp twenty euro note' at a self service machine for a 'measly' single ticket from Lansdowne Road to Dun Laoghaire.
"They gave me all that coinage and I have no room to put those coins anywhere. I wear a slim fit, hand-fitted Hugo Boss suit."
Irish Rail's Barry Kenny says there are ways he could avoid a repeat and save money.
"Get the Leap card, because it's a no-change situation there. And if money is as tight as his trousers, he'll also be able to save up to 31% on his fare", he said.
Needless to say the internet has responded with due mirth.
Comedian Emma Doran has set up a fundraising page to help get Tony a Leap card.
Let's just hope Tony's slim pockets have room for it!
