Here's the video where the famous quote was first uttered. (He says it at about 2:00.)
Some background:
A University of Florida student who was filmed being shocked by police with a Taser stun gun after persistently questioning Sen. John Kerry will not face criminal charges and has apologized for his actions, his attorney said Tuesday.
Andrew Meyer, 21, yelled "Don't Tase me, bro!" as he scuffled with officers during the on-campus speech last month. In letters to the university, its president and the campus police department, he apologized, attorney Robert Griscti said.
"I made the decision to supersede the rules, and for that I apologize," Meyer wrote. "I should have acted calmer and obeyed the directives of the officers. If I had, none of the subsequent issues would ever have arisen."
