The Case of the Fickle Filly - S6-E11
Other mistake: George Tabor parts his hair on his right side, however when Perry cross examines Mr. Tabor his hair is parted on his left and then reverts back to his right side. The two dots on his tie are one low and one high, they also switch. The negative must have been flipped.

The Case of the Fanciful Frail - S9-E24
Other mistake: Park Milgrave finds a small chest full of realistic counterfeit money in Bruce Strickland's apartment. (Counterfeit money was not used for this scene. The chest actually contained three stacks of dollar-sized paper with a real bill on the top of each one.) Milgrave dumps the money into a metal urn and lights it on fire but the money he dumps out is play money, which does not look even remotely like real money.
The Case of the Pint-Sized Client - S2-E3
Other mistake: In an abandoned house, a 14-year-old boy finds a satchel filled with money taken in a holdup at a finance company. He uses $50 to buy a robe for his grandfather, then hides the rest of the money in his grandfather's house. During the trial of the grandfather, who is accused of being one of the holdup men, the police lieutenant says, "We found all the money except for $12,000. We conducted a second search of the home and found the rest of it." He should have noted that $50 was missing.
The Case of the 12th Wildcat - S9-E8
Other mistake: Perry, Paul and Della attend a Wildcats football game at the Los Angeles Memorial Coliseum. Stock footage shows a packed stadium. After the game ends, a close-up shows the three exiting the stadium along with several other people. The next scene takes place outside the entrance to the Coliseum. In a long shot, only two cars and six people are visible. In 1965, the Coliseum's seating capacity was 101,574. Where did everyone go?
