00:00 This episode of "Stuff You Should Know" is about the history of Bachelor/Bachelorette parties.

05:21 Bachelor parties originated in the late 19th century as a way for men to have one last opportunity to see a naked woman before getting married, but today, they often make people uncomfortable and are seen as unnecessary, with many people preferring more low-key celebrations like camping or hanging out with friends.

10:48 Bachelor and bachelorette parties have a long history across different cultures, with some traditions involving rituals and others involving humiliation, but it is generally agreed that having a wild party the night before the wedding is a bad idea.

16:12 Bachelor and bachelorette parties originated as a way to celebrate the end of single life and the transition into marriage, with some parties in the past involving scandalous and extravagant activities.

21:21 Bachelor parties gained a bad reputation after scandalous events like the Sealy dinners, but Emily Post claimed they were actually tame, although a Rhode Island French Canadian textile worker's oral history contradicted this and described a raucous stag party.

26:44 Bachelorette parties evolved from bridal showers in the 20th century and became more similar to bachelor parties in the 1960s and 70s, with the rise of "personal showers" where sex toys were given as gifts, and in the early 90s in the UK, "hem parties" became popular, while in the US, the arrival of the Chippendales review in 1979 is credited with kicking off the bachelorette party industry.

32:12 Bachelorette parties have evolved to include body scavenger hunts and extravagant activities, with the rise of the party industry and people getting married later in life.

37:35 Bachelor and bachelorette parties are still predominantly of the stereotypical kind, but more people are opting for alternatives that suit their preferences and are not interested in the traditional raucous celebrations.

42:45 Movies like "Bachelor Party" and "The Hangover" have become quintessential bachelor party movies, with the latter being considered a very funny film.

48:14 Bachelor and bachelorette parties often involve kidnapping the bride or groom, with Australian parties taking it so seriously that they have to warn against doing it in broad daylight on the street, and some parties can go too far with practical jokes, such as getting the groom drunk and putting his leg in a cast without telling him until after his honeymoon.

53:50 Bachelor and bachelorette parties have become a way for people to showcase their lives on social media, with some even spending money just to have Instagram-worthy photos.

59:10 The narrator and Volker find themselves in a dangerous situation after landing on a private runway in the Amazon without permission and being surrounded by armed men.
