In Season 10, Episode 8 of South Park, called "Make Love, Not Warcraft", the boys had to kill boars in World of Warcraft to level up all the way to 60. This was in an attempt to defeat "the one which has no life".
A YouTuber, Dr Five, has taken the same journey, completing the World of Warcraft: Classic boar challenge.
To quote Eric Cartman from the iconic South Park episode: "You can just hang around outside in the sun all day, tossing a ball around, or you can sit at your computer and do something that matters."
World of Warcraft: Classic boar challenge
This challenge was already completed in normal World of Warcraft but never in World of Warcraft: Classic, until now.
In the South Park episode, the boys had to kill 65,340,285 boars.
Dr Five slaughtered over 10,000 boars in World of Warcraft. This immense feat took him 9 days and 18 hours of in-game time, or 234 hours.
Warning: The video below has some explicit language, as Dr Five finally hits level 60 by just killing boars in World of Warcraft: Classic.
The ultimate "ding" takes place at the 1:50 mark.
Dr Five did not go through Elwynn Forest as the boys did in South Park. Instead, he killed boars in Dun Morogh. Then, he proceeded to kill boars in several different World of Warcraft: Classic zones.
These include The Barrens, Redridge Mountains, Blasted Lands, Razorfen Downs, and more.
His journey came to an end in the Eastern Plaguelands, where he became the first person in the world to level to 60 in World of Warcraft: Classic by only killing boars.
You can watch through the entire boar challenge playlist on Dr Five's YouTube channel, which consists of more than 50 videos.
