Believe it or not, there are people out there who have absolutely no idea who Michael Jordan is. There are also people who have no idea who Derek Jeter is. And yes, there are even some people who have no idea who Floyd Mayweather is. But in the video above, which was filmed in London recently, Mayweather can't believe his ears when a woman tells him that she doesn't know him.

Watch the clip to hear Mayweather try to tell the woman that he's a man of great importance. Very entertaining (and possibly humbling?) stuff.
