There's only a few weeks to go until the big fight between Conor McGregor and Floyd Mayweather on August 26th.
If you're excited, a Kildare teacher has taken it to a new level and wrote his own song about the Notorious.
Mick Konstantin shared the song last night, called "There's Only One Conor McGregor", and it's already clocked up more than 1.7 million views!
McGregor himself even shared it on his own Facebook page.
It's not the first time Konstantin has done something like this- he recorded a track for Euro 2016 last year too.
