Glad I'm not the only one who thought of that scene - I was going to post about it if nobody else had. Gets me every single time.

There were also some comments made about bullying and rivalries between cast members on Salute Your Shorts.

Actually, YCDTOT is talked about to a fair extent. Roger Price, Abby
Hagyard, Alasdair Gillis, Christine McGlade and a couple other people
involved in production were interviewed for the book. I'm not sure I'd buy it if that's the focus you're looking for, but it'd be worth checking out from the library or some such.
