Roberto Luongo loses his cool and goes after Cizikas on Wednesday night!

Veteran National Hockey League goaltender Roberto Luongo is known as a friendly and funny kind of guy, but even friendly guys have their limits.

On Wednesday night with Luongo's Florida Panthers facing off against the New York Islanders we saw an incident take place in front of Luongo's net, one where Islanders forward Casey Cizikas knocked off Luongo's helmet.

It's hard to tell from the angles in the video below, but it looks like Cizikas may have attempted to grab onto Luongo's head while he went down, although that may have been merely in an attempt to brace himself. 

Luongo didn't appreciate it won't bit, and earned himself a roughing minor for going after Cizikas in the ensuing scrum.
