Isshu in episode 26 while under the love spell, when trying to impress Nanami after Yousuke and Kouta told Isshu to give Nanami a cute animal as a gift. The cute animal that Isshu gave her, a cow. It's hilarious.
Episode 46, aside of that one crossed with Crowning Moment of Awesome, there's Nanami taking her cooking for Kagura/Lady Gozen into Serious Business to the point of translating every of her stoiccommentaries into either insults or praises to her cooking.
