Gunn had a "fantastic rapport with the Norwich supporters". As a player, he liked "to tease the crowd during the game". Before each half of a match, Gunn would run toward his goal and pretend to attempt to headbutt the crossbar. Gunn says this is a habit he began as a youngster, and cannot remember how or why he began to do it. Norwich fans noticed it soon after his arrival at the club and, in Gunn's words, "would wait until I got to about the 18-yard line and then start a small "Wooo..." which would build into a full-blown "WOOOO ... AH!" ... I loved it and came close to smacking my head against the woodwork a couple of times". During play, he would cup his ear, which would prompt shouts of "Bryan, Bryan, give us a wave".
