Chicago Bulls forward Bobby Portis is well aware of the nickname he's been given.
Earning the less-than-flattering moniker of "Crazy Eyes Portis" because of his protruding eyeballs, the 6-foot-11 rookie is also known for his on-court exploits.
This block on New York Knicks big man Kyle O'Quinn, for instance.
The ball goes out of bounds - with the Bulls gaining possession - and O'Quinn appears to be nonplussed by Portis' efforts.
