Conor McGregor vs Floyd Mayweather.
Don’t lie – you’d sell your organs or some cherished family members to watch this fight.
But now it seems like the Irishman actually has his heart set on a megafight with the unbeaten (and now retired) boxing champion.
Comments he made in the run-up to his UFC 196 welterweight bout with Nate Diaz firmly put him open for business for fighting the 49-0 American.
The prospect of a McGregor vs Mayweather fight first reared its head in the wake of the so-called ‘Fight of the Century’ between ‘Money’ and Manny Pacquiao.
The Dubliner said he would beat Mayweather in seconds in a street fight – because ‘when you don’t know how to grapple you don’t stand a chance.
‘I would knock him out cold,’ he crowed.
But McGregor now says he would be open to discussions on fighting Mayweather in a boxing ring rather than the octagon.
“I’m open to that discussion, come at me,” McGregor told BT Sport. “I hold the key to the fight game. I am open minded, I am open to discussion. I love competition, I love fighting.
“It would be nice to make that fight if the fans are interested to see it and obviously they would.”
MMA journalist Gareth Davies reckons it would be a billion-dollar fight – numbers that will probably be ringing in McGregor’s ears.
