Contains some innuendo throughout the course of the series.
A recurring character is frequently referred to as a pervert, as he makes suggestive remarks about other characters (including male characters). He often exposes his body (for example, by ripping his shirt open and rubbing his chest) in order to make other characters, particularly girls, feel uncomfortable.
In episode 18, it is implied that two characters (adolescents) lose their virginity to one another (the line "I want to make love to you" is repeated frequently throughout the episode). The only visual implication that they have had sex occurs in one shot in which the two characters are seen lying in bed together. Their bodies are completely covered from their necks down. This incident is referred to infrequently and discreetly throughout the remainder of the series.
A girl falls on top of another, and another girl teases them by calling them "lesbians".
On occasion, characters will have inappropriate fantasies that are pixellated for comic effect.
