Funny / Princess Lover!

• EVERYTHING in the Hot Springs Episode, from Sylvie constantly carrying around her sword, to Super-Deformed Yuu's Corner of Woe, to the constant Fourth Wall Breakage, to the whole episode running on Rule of Funny and Mundane Made Awesome. Not to mention all the attempts from a suddenly-Genre Savvy Teppei and co in trying to abuse his main character status to become an 'Accidental' Pervert, which backfires spectacularly.
• Haltman getting caught falling off his train by Charlotte's butler, and then being thrown into a river by said butler when he realized Hartman wasn't his beloved Ouju-sama.
