When the poker game is first held up, Veronica (Kristen Bell) turns to face the masked robbers. As she does, her black hair falls over her neck. When they cut away and back to Veronica again, her hair is pushed back over her shoulder, revealing her necklace.
The necklace the little girl is wearing is tucked inside her shirt when she approaches Veronica's (Kristen Bell) car, but when Veronica reaches out to reclaim it, it's suddenly outside her shirt.
Around the end of President Evil (2006) (S03E05), when Veronica sees the school bus coming with the policeman's daughter in it, she is putting on her seat belt. But when the girl comes to her window, she is not wearing her seat belt.
Veronica (Kristen Bell) gives her college email address with a suffix of .org, however colleges and universities use the suffix .edu; .org is used by non-profit organisations.
When Veronica (Kristen Bell) goes to see Weevil (Francis Capra) at the station, Sheriff Lamb (Michael Muhney) pretends to be a robot while talking to her. You can hear an off-stage extra say "Hey, Sheriff's doing the robot. I'm gonna get my camera phone."
