If you don't know the name Conor McGregor by now, then we're not sure what to tell you.
The Irishman has taken the MMA world by storm since recording
a 67-second TKO on his UFC debut against Marcus Brimage a little over three years.
On Wednesday night, The Notorious marked the date with a reminder to all that he is still the king-maker.
The Dubliner has been uncharacteristically quiet on social media after tapping out to Nate Diaz at UFC 196, but he was back to his trolling best as he marked the occasion.

McGregor is being typically verbose but he has a point.
UFC stars such as Diaz, Demetrious Johnson, Donald Cerrone and many, many more have all spoken about wanting McGregor-type pay-days for their fights. By headlining major events, McGregor has helped breach attendance and pay-per-view records for the promotion.
With a cock-sure statement like McGregor's, there were always going to be some UFC fighters out there that reacted.
Rory MacDonald took the tweet in good humour.

Light heavyweight Ilir Latifi also made his debut at that UFC event in Iceland and shared McGregor some love.
