In case you somehow don't know, Conor McGregor is in Nevada to take on Jose Aldo for the UFC featherweight title, and his fans have crossed the pond in their thousands.
But The Notorious isn't the only one there in the States to see, as this Irish fan proved during a Q&A session with Ronda Rousey's conquerer Holly Holm.
As the unnamed Irishman shuffled up to the mic, he apologises for whoever it was who came before him and promises to ask a serious question - before breaking into a perfect rendition of an old classic.
Obviously, the crowd lends him a helping hand...
