Audio problem: When Greg and Peter were in the family room helping Marcia write a letter to Davy Jones, Peter suggests telling him that he won a $10 million sweepstake. Then as they walk into the kitchen, you hear Greg saying "A $10 million sweepstake" and Peter says "$20 million?" It is clear that he wasn't really talking, because the sound of his voice is very distant, although they were only in the next room.
Audio problem: At the end of the show when Alice is blowing the whistle, the whole family comes to the top of the stairs. Mike says "Alice, it's 6 o'clock in the morning" Watch his mouth. It looks as though he curses and the (curse) word was dubbed out.
Is There a Doctor in the House? - S1-E13
Audio problem: When Mike walks into the kitchen and sees the chart with the list of kids on it and what ailments they've had, he comments on one of the ailments, saying "None of the kids have had distemper." However, if you watch his mouth, he appears to have originally said "rabies."
Audio problem: When Marcia comes downstairs before the dance Alan shows her his new braces, and as they both head toward the door we hear the clear sound of shoes walking on a wood floor, even though they're walking on carpet. (00:23:50)
Audio problem: When Carol calls and Mike answers the phone, (after Cindy runs and then the entire salad (bowl) falls to the floor) you can hear Marcia and Jan arguing in the background, but that exact (said) audio is looped if you listen closely - it is an argument from an earlier script that is repeated about 6 times or so during the length of Mike's phone call from Carol.
Snow White and the Seven Bradys - S5-E3
Audio problem: When the kids are painting a cardboard tree for the play, they ask their dad what he thinks of it. He then says "you better ask the two poodles next door." As he walks away he seems to almost trip/fall over something. Then the mom is heard laughing, even though she's not in the scene.
Audio problem: In the scene where Mike comes home and Carol has ruined his golf club, you hear a door open and close, with a latch/doorknob. She hears it and knows he is home. But he comes in the back door, which was a sliding (glass) door. (00:20:00)
Audio problem: Listen to the sounds as the family eats dinner; the same sound sequences keep playing. For example, one sequence of three quick taps of silverware on plates plays several times, followed by another sound that is difficult to identify. (00:21:15)
Audio problem: Tiger is heard barking as he runs down the stairs, but it's obvious the dog isn't barking at all. (00:06:05)
Audio problem: Alice's comment to the girls while handing them their books was obviously dubbed; there's an unusual echo quality in the sound. (00:03:05)
The Hustler - S5-E21
Audio problem: Bobby is lining up a pool shot. There's a cut to Cindy, and as she says her line, the sound of pool balls being hit is heard. But when the pool table is shown again in the next shot, none of the balls have moved. Also the pool table moves from outside to inside. Lots of mistakes with the balls on the table throughout the game. (00:08:25)
Audio problem: Before Mrs. Johnson leaves, she says something to Carol (looks like "I really am"). But there is no sound. (00:15:30)
Audio problem: When Peter is hinting to Carol that he is still growing, the audio changes to being dubbed in from Peter separate from the actual scene after Peter stands up and mentions he wants cowboy boots. Then the audio is back to normal once Peter mentions "Brown" cowboy boots.
Audio problem: Many times throughout this episode, the actors' voices echo, especially when Mike yells out to Peter (and vice versa) from different rooms.
