Mashiro-iro Symphony/Funny

The bath scene in the first episode, where Sakuno walks into the bathroom attempting to join Shingo in the tub. Shingo adamantly refuses for obvious reasons, while Sakuno maintains the argument that it's alright because their siblings. At least she kept her towel on.
Episode 3, where Shingo and Co. run into Airi (who at this point is still assumed to be the Ojou) in a low-class supermarket during a massive sale. Cue Big No.
The entire 'maid tournament' conversation in episode 5. Angie's declaration that Shingo is her 'maid rival', Inui wanting to wear a maid uniform only to be told she's a bit small and her reaction, and at the end Angie's sudden Moe breakdown at losing her maid headband.
Episode 6 one-ups the bath scene in episode 1, this time with both Angie AND Sakuno attempting to join Shingo in the bath. Unfortunately for Shingo, this time BOTH their towels drop off. While they're trying to pull him out of the bath no less.
The shopping trip in episode 7. Specifically, right before the shopping starts, when Shingo and Sana are both waiting there. Actually, truth-be-told nearly everything Sana does this episode.

Shingo: "What should I do to make you recognise me as a club member?"
Sana: "Become a girl. And don't get within 10 meters of 'Miu-senpai'."

Episode 9. Miu's Hot Mom. That is all.
- And later when after Shingo returns to her house to get his cellphone (which he left behind), he gets an eyefull of Miu without her clothes as she's running after her cats. At first she's delighted to see him, until she realizes what he sees in front of him. Miu's mom actually doesn't get upset at all and even advises him to pretend he didn't see a thing when he meets Miu in school the next morning.
