• Dokkan! episode 19 is full of this. Hazuki being a Covert Pervert? A little boy running onscreen with his genitals exposed? Hmmm.
• There's also Onpu groping Mutsumi's breast, Mutsumi making a rather suggestive remark about Hasebe encouraging her to wrestle, and shots of the boys doing their business in the bathroom. Not to mention, despite that it was sung by a bunch of adults in-show, the insert song, "Namida no Broken Heart", has some racy sexual imagery in its lyrics about a summer fling...
• Some episodes have nudity used for comedy, odd closeups of lower areas (male or female), episodes mentioning puberty and even double entendres.
