Holes are the theme and center of anxiety in this episode. Don't get your hopes up, though.
Galko is self-conscious about her crooked teeth from watching a movie where an American woman got braces to straighten her teeth. Japanese society is a relative latecomer to orthodontics and correcting crooked teeth. They have been turning crooked teeth lemons into lemonade for a long time, saying they are cute, but they are more conscious of the fact that foreigners use braces and other correction methods to straighten their and their children's teeth.
Galko was also impressed by a handsome black actor in a movie and Ojou states how melanin in people's skin can make them different hues, but the mucous membranes in the vaginal vestibule and internal genitalia (and don't forget the anus, y'all) is not pigmented and is pink for most everyone. Thanks for straightening that out.
Galko likes horses, but Otako warns her that she could tear her hymen by riding horses. Ojou blurts out that she rides horses at her villa, but is horrified by this warning. She states in a panic that she has never bled while riding horses. She ought to just ride the pink pony and dispel such worries.
Galko is angry that she gained 200 grams (just how accurate is her scale, anyway?? 200 grams is 7.05 ounces or 0.441 pounds.). Otako admonishes that is nothing and that she'll lose that weight by peeing once. Otako says that when dieting, women lose boob fat first (because the gods are capricious and cruel?). The buxom and chubby Nikuko (Nikukocci) said that is a myth as she lost weight in middle school but not boob size, stunning the boys in the class with them imagining such a busty junior high-schooler.
Galko is horrified of pierced tongues. She remembers asking her older sister about getting her ears pierced and was teased with horror stories about dental drills. Otako teases her further by a story about how a white string can come out of your pierced ear. Galko has heard that if you pull on the string you'll go blind, but your optic nerve does not go through your ear (good thing, too), so that rumor is bogus. Otako instead tells a story of how a woman's large hoop earring got caught on a passing truck's hook with disastrous effects. Otako calms Galko down by showing statues of the Buddha having pierced ears, but that was before his enlightenment when he was a swanky prince. Galko instantly forgets any piercing-related worries.
