Thanks for the reply. Yeah, his appetite is definitely canon. ;) I remember the scene where Jennifer is in Brian's office and tells him Justin eats like a football player. But to me that implies that she has a rather large grocery bill each month not necessarily that he eats a lot of junk food.

My problem is I don't recall Justin ever ordering anything in the diner. It seems that most of his scenes in the diner were of him working. I know in the first episode Michael orders a bacon cheeseburger for Justin the night he introduces Justin to Debbie.
