You Better Shop Around (2) - S5-E22
Revealing mistake: Marcy is stacking cartons of eggs in her arms. She turns around and a carton falls on the floor making a busted egg sound although the cartons are obviously empty.
Plot hole: After Al steps out of the coyote doody he goes to Bud and puts an arm around him. Then they walk together towards the same spot - without looking down. (00:03:35)
Revealing mistake: When the bailiff pours rum into the judge's jar, it's obvious that there's nothing coming out of the flask. (00:13:05 - 00:14:10)
You Better Shop Around (2) - S5-E22
Revealing mistake: When Jefferson starts to shove the 'regulation Foodies cart,' it's very obvious that the actor makes the shaking movements of the cart by himself. (00:08:05)
You Better Shop Around (2) - S5-E22
Plot hole: The supermarket director orders the photographer to take a photo of Al's special shopping cart. Then he turns around a little towards the cart. When the camera flashes, his right shoulder has to be in the whole left side of that picture. (00:07:50)
You Better Shop Around (2) - S5-E22
Revealing mistake: When Al 'bowls' Jefferson out of the way you can see the stuntman jump high and fall back into some kind of holding wire. It's an annoyingly bad stunt. (00:19:45)
You Better Shop Around (2) - S5-E22
Continuity mistake: The manager gives Jefferson a "wobbly" cart to use, but for the rest of the episode it's a normal, fast moving cart.
Visible crew/equipment: At the beginning of the Last Will reading we see that there's no-one sitting left to the female notary. But in the close-ups there is a small round silver-shining object at the right edge of the picture - left from her. Must be some equipment. (00:04:20)
Visible crew/equipment: When Peggy enters you can see the shadow of someone's head at the left edge (the kitchen). It can't be anyone of the actors. (00:12:05)
Continuity mistake: The out of order sign on the toilet changes position between shots. It's level at first. Camera cuts to other men. When it cuts back to Al it is tilted. (00:18:18)
Continuity mistake: Kelly knocks the lampshade off the lamp. Next shot shows it put back on although no-one is around it.
You Better Shop Around (2) - S5-E22
Continuity mistake: When Jefferson and Marcy are getting ready to take off during the supermarket race, Al sprays the floor with oil causing them to slip. Being that it is fresh oil, their clothes should have oil stains. But in the next scene, Jefferson and Marcy are perfectly clean.
Revealing mistake: When Al slams Kelly's date's head on the banister it moves back and forth indicating it's made of rubber.
You Better Shop Around (2) - S5-E22

Oldies but Young 'Uns - S5-E17
Other mistake: Just before Charlie and his son leave Peg says "Charlie, my watch". Implying that he took it off her wrist. Yet during the whole scene she didn't have a watch on her wrist. It appears in his hand out of nowhere.
Weenie Tot Lovers & Other Strangers - S5-E18
Revealing mistake: When Peg opens the last weenie tot box, notice that only a ticket falls out. Meaning all the boxes had no tots in them just tickets.
Kids! Wadaya Gonna Do? - S5-E19

Visible crew/equipment: Right after Jefferson walks out after saying what he was in jail for, when they are showing Bud and Al, you see a large head shadow go across Bud's leg from left to right.
Weenie Tot Lovers & Other Strangers - S5-E18
Continuity mistake: When Al asks for the checkbook to write a check for Bud, Bud puts his right hand on Al's left shoulder. Next shot, Bud's hand is coming off Al's right shoulder.
Other mistake: Bud calls a late night sex hot line which is a 1 900 number yet he only pushes 6 digits on the phone.
Answer: It was one of the hoses connected to the engine, nothing specific, but to indicate that Al tampered with the vehicle.
