Floyd Mayweather -- Some of My Best Friends Are White!

Floyd Mayweather couldn't possibly be a racist ... because he employs sooooo many white people!

The boxing superstar has been in hot water ever since he tweeted that New York Knicks guard Jeremy Lin was only receiving attention because he was Asian.

Mayweather has stood by his words and when he was asked about it yesterday, he proceeded to mention all the white people around him ... even pointing out that one of them "does a tremendous job."
