Norman Brenner appearances

Does anyone have a full conclusive list of all the episodes that Norman Brenner has appeared in, (I look in Mike's general direction)? He is the extra with the English accent and light orange hair. Looking on the epguides site, they list about a dozen or so episodes he has been in, but I know I have seen him in many others, probably about half of all of them. One example that is missing is the guy sitting next to the door in "The Chinese Restaurant".
