i knoooowww!!!!! I love his characer! i found it on wikipedia:
Bruce the Performance Artist - Mustached man who speaks in a calm, drawn-out voice with a slight lisp, with the catchphrase of "Oh noooo". His first appearance was in the episode Chitty Chitty Death Bang, where he was a horror novelty shop clerk. His name was finally revealed to be Bruce in the season five episode No Chris Left Behind. In The Cleveland-Loretta Quagmire he teaches a CPR course, and appears on the school board committee of James Woods Regional High School in Peter's Got Woods and No Chris Left Behind; in Petergeist he is shown as being a medium with Native American spirits, and in Peter's Two Dads, he is a hypnotherapist. As evidenced in the episode Stewie Kills Lois Bruce may have a boyfriend or relative living with him named Jeffrey (as heard in the episode McStroke) whom he may have met in "No Chris Left Behind"; this character is not seen, but he sounds very similar to him. During the Star Wars retelling by Peter, he is playing the character of Greedo. Several non-human characters, most of which are out of pop culture, have appeared with the exact same voice and mannerisms as Bruce. Voiced by Mike Henry.
