In episode 5, at the end of the day, Ritsuko asks everyone if they didn't forget anything, to which they say yes. Cue the Producer, buried under a sand castle, weakly saying "You forgot something..."
In episode 8, there's the Runaway Bride's turn-around when she finally meets her arranged groom; from stubborn refusal to eager acceptance in five seconds.
In episode 9, after RK shoots for a mini-drama, Iori decides treat everyone with special pudding...only to find that all of it vanished. So, Ami and Mami spend most of the episode, as spies, trying to figure out who did it. They went as far as dressing as giant pudding, scaring poor Haruka out of her mind. Miki finally announces that she's the one who ate the pudding. But, at the epilogue, she says that there was only one left. Notice how Azusa is the only idol doesn't appear a lot in this episode. That's because she's the one who really ate all the puddings...despite being on a diet, as she briefly mentioned in episode two.
In episode 10, when Makoto and Iori were asked to bring an item, they bring The Producer. Required item? Office Chew Toy.
Makoto's boyish charm works again...even to a rival team's member.
Episode 15 about the variety show has a bunch of them. Of note, Haruka has trouble opening a box of pastries and after struggling, it pops open, hitting her squarely on the nose... and Chihaya stifles her chuckling. This is based off of a memetic video of their respective voice actors doing the same thing on another live-action show!
Yukiho suddenly having some weird fetish for dressing Makoto up in different outfits.
In episode 26, Yukiho, Haruka, Makoto and Chiyaya all go out to a karaoke bar. All of the girls get pretty impressive scoring in their singing, except for Chihaya who gets a sixty. She then tries to improve her score, which she does, point by point, song by song. Once she finally gets a perfect score, the other girls are seen exhausted.note To add to the hilarity, all the songs that Chihaya bombed were actually her own image songs from the series. Songs she probably practiced every day and sang hundreds of times and she still gets low scores for them! As a last bit of amusement, the song she finally aces, "Saa! Asagohan Tabete!" (Eating Breakfast) is a cheerful song that's completely at odds with Chihaya's usual style.
Chihaya's obsession with naming Puchidols "Gonzales," only to be turned down every time.
Ritsuko, Takane, and Yukiho demonstrating their show idea in Season 2 Episode 50, complete with live action puppet versions of their Puchidol counterparts.
