Doug's Fat Cat / Doug and Patti P.I. - S3-E1
Continuity mistake: Doug and Patti P.I.: When Doug and Patti tackle Skeeter, they pin him down, and Patti's hands are on the left side of his chest, and Doug's hands are on the right. In the close-up of Skeeter, their hands have switched sides; then go back to normal in the next shot. (00:20:03)
