The only heckles I recall being involved in are at the Ralph. When we opened the season in 2005, I got front row seats on the 30 or so (opponents side). Me and another rando Bills fan were harassing, in a fairly friendly manner, Texans CB Phillip Buchanon all day.
When Carr threw either his second or third pick, can't recall which, we yelled to him "Hey PBuck, wish you had another QB!" and he straight up turned around and nodded his head to us.
