Revealing mistake: At the end of the court session when Karen pulls the whoopee cushion gag, you see Will's chair right before he sits down and there's no whoopee cushion.
Other mistake: During the court hearing the cop Vince mentions looking in the trunk of Karen's car. Nowhere in the scene prior when he stopped them did he look in the trunk.
