There are plenty of memorable Brooklyn Nets fans, from Mr. Whammy to Jeffrey Gamblero to, of course, the Brooklyn Brigade. One other notable fan is Daniel Weiss, aka Cowbell Guy, who bangs his cowbell to get the fans pumped up and in an attempt to make the opposing team miss their free throws.
Mr. Weiss is, indeed, a huge Nets fan. Make sure you say hello to him next time you're at Barclays and help in his efforts to bring the noise.
