Continuity mistake: Carrie enters and says "Bad news", to which Doug replies, "Ya, if it's about being out of mini donuts, I'm aware and I'm not happy". However, in S7 E7 "Offtrack...Bedding" at the start of the episode Doug says he doesn't like mini donuts. (00:00:30)
Continuity mistake: When Doug is in the porta-potty you can see a tree outside the window to the left; however when Doug looks out the window we can see their are cars parked on the side where the tree was. (00:12:40)
Suggested correction: Not really, the shot where the tree can be seen is viewed from the front so the tree is actually behind the porta-potty to the left. The view to the cars is directly looking left.
Continuity mistake: When Doug jumps out of the porta-potty before the rival ice-cream truck smashes through it, the door is open and Doug immediately lands on the ground; but when the shot changes, the porta-potty door is closed and we can't see Doug rolling onto the ground. Also, when the truck smashes into the porta-potty, liquid splashes everywhere; but when we see Doug in the next shot he is dry and no liquid on the ground around him. (00:12:55)
