These days Conor McGregor is perhaps the most prominent athlete in the UFC, with his face appearing just about everywhere.
But you'd be forgiven for seeing this picture of him back in his school days, sporting a serious bowl-cut, and having no idea who you were looking at.
The Tallaght Echo shared this picture to their Twitter account on Monday evening.
Look at that smile! Who knew that one day he'd be beating the living daylight out of muscular men for money?
