I'm envisioning it as a running gag for the show. 5 episodes in, it's shown that the clip is taken out to the garage for disposal where they have a huge stack of clips from previously bought bread. 2 seasons in, it's shown in the background that a separate garbage collection vehicle runs up to the driveway and a specially built clip hauler is used to pick up the clips. Another season in, a bread bag clip recycling station is passed while the main characters are driving somewhere. Etc.
