The last one I dropped... last night, Punchline. Japanese word game: Panchira-inu, with panchira being obviously 'panty shot', and inu is either just the ending so it creates the Punchline word, or dog, where both of these meanings make sense.
Why I dropped it... ever read Oretama? My Balls in English. A manga series where the main character can't ejaculate or the world will end. This anime has a similar premise: the main character can't get too excited or the world will end. What does this series give us... Power ups (a.k.a Hidan no Aria), panty shots and absolutely no sense. Worth noting: in Oretama the story is shown in an interesting way, the plot goes forward and makes you want to read more (and it's borderline ecchi), and moreover, the whole 'world will end' scheme is EXPLAINED. Here it's just a way to excuse panty shots.
