Check out what I'm watching on Crunchyroll! http://www.crunchyroll.com/oresuki-are-you-the-only-one-who-loves-me/episode-7-i-discover-an-unexpected-side-790234
This episode especially made me laugh, in a pretty steady symmetrical fashion. Perhaps helps that the jokes with Sun-Chan just made me cackle louder. Their trip to the pool is just filled with reasons to laugh, while somehow maintaining the pseudo-serious tone of the series; it really worked for my funny bone.
Oresuki is probably worth watching for the twisted-characters and wise cracks about rom-coms, but this episode is just worth watching, period.
