Floyd Mayweather believes everyone in the world knows who he is. When someone actually tells him to his face that he or she doesn't know who he is, he is completely baffled.

Don't believe it? There's video to prove it.

While in London, a stranger told the boxer that she had no idea who he was. That led to this interaction.

Warning: Video contains NSFW language.

The woman did not know who Money May was, but she knew who Jamaican runner Usain Bolt was. That made Bolt feel better.
