Aquaticism - S7-E14
Continuity mistake: Near the end, when Roger is talking to Judy, he has a tie on. But in side shots of him, he has no tie on.
The Secret Ceramics Room of Secrets - S8-E9
Continuity mistake: At lunch, Gene has a straw in his milk. But in shots of just Gene and Louise, there's no straw.
Continuity mistake: When Linda and the kids are walking back home, Linda doesn't have a fire hat on. But in the shot of just her, she's wearing one.
Factual error: Linda calls up Jen the babysitter to come watch over the Belcher kids, so she and Bob can go to Maya and Beckett's loft "party." Jen is in her room talking to Linda over the phone, however her screen still has the red (decline call) button and the green (answer call) button with Linda's name as she talks on the phone. There should only be the 'hang up' button with Linda's name and a running time of the duration of their call. (00:04:22)
Prank You for Being a Friend - S10-E22
Continuity mistake: When Louise is in Mr. Frond's office taking about Kaylee, in shots of both of them, there's no file on the table. But in shots of Mr. Frond, there's a folder next to him.
Answer: It's a made up song for the show. It's a synth version of what the kids sang in Mr. Frond's video at the beginning of the episode. "Let's Swap Eyes."
