The DVD Commentary by Roger Waters and Gerald Scarfe is a fountain of these:
- During the animation of the flowers in the song "What Shall We Do Now?":
Waters: What are those flowers, doing Gerald?
Waters: That one's turned into a carrot!
- Waters' response to Pink screaming "STOP!!!" towards the end.
"We're right here, Bob, no need to shout."
- During "Is There Anybody Out There?", while Pink frantically tries to escape the wall, Roger "narrates" Pink's thoughts with an Irish accent. He even throws in references to The Troubles!
