Duel Distractions: Part 1 - S1-E36
Continuity mistake: A woman walks into the classroom holding an abandoned bag. When Banner asks "May I help you", the woman's hands are positioned outside of the straps, but when the shot cuts, her hands are inside of the straps. Also, during the shot, she has her right hand off the bag, but when it cuts to a close-up of the bag, her right hand is suddenly holding onto it. (00:04:35)
