From Episode #101, The Case of the Wandering Widow
Riley Morgan Out Of Place

Yep! There's Riley to the left of Perry's head sitting in the audience while he's being questioned on the witness stand. This picture was cropped to show only the upper-left part of the frame. (Thanks to FredK for reporting this one.)

Here's a close up shot of Riley. The angle is different, but the two people behind Riley's head seem to match up with the previous picture.
Bouncing Roger

Roger at location 1. (Thanks to FredK for reporting this goof.)

Roger at location 2. (Thanks to FredK for reporting this goof.)
Magic Donut

Jimmie at the top of the steps: No donut. (Thanks to FredK for reporting this goof.)

Jimmie at the bottom of the steps: Donut in hand. Actually, the donut appears at the cut as Jimmie begins to go down the stairs.
