Here is the elaborate (embroidered?) and possibly incriminating sign one Floyd Mayweather fan made to show his support in Las Vegas.
Now, by "illigal Mexican," I assume this person means he is in the U.S. illegally, not that his entire existence/Mexican-ness is somehow illegal. If so, uh ... maybe don't display that on a huge sign? "I am breaking the law right now" doesn't seem like a good message to broadcast, especially if you're trying to stick around to catch a sporting event. Just a thought.
But really, good luck, good sir. I admire your enthusiasm.
