Pound-for-pound fighter Floyd Mayweather Jr got into a verbal spat with a woman at a barber shop in London when she claimed that she didn't know who he was.
The American unbeaten boxer is believed to have been getting his hair cut in Brixton, South London when he discovered that a Jamaican woman in the room had no idea of his identity.
A video of the spat has been uploaded onto Spiff TV showing the woman say that she knew who Mike Tyson was, but had never heard of Mayweather.
The boxer responded by telling her to check out Forbes' rich list.
