identity of Gonzo's main heckler

[superboober]

Looking over the Season 1 set, it seems that whenever Gonzo launches into one his acts, there's one audience member who leads the booing more than the others each time. Who from the usual audience shots do you suppose it is? (I think we can rule out Sam in the back, as it sounds nothing like him, even though he probably wouldn't consider anything Gonzo does to be "culturally uplifting").
