Who dunnit? Who shoved the bottle up the ass that broke the Proto-Finnic Holy Roman Khaganate's back? In this episode of Based on What?, the boys take a deep dive into the complex web of ethnic hatred and memes that is the Balkans, and physically attempt to recreate the infamous "bottle-in-ass incident" that defined Serbian politics for nearly 15 years. Next, they crawl into a snowdrift next to Simo Häyhä, the greatest sniper of all, and blast Russian conscripts with only ironsights - and a ton of vodka. Then, they put themselves into the minds of the serial killers, cultists, and political radicals who have left trails of blood on the dark streets of Tokyo. Finally, they dive deep into the early history of humanity, and the great conflict that shaped all of mankind: THE FINNO-KOREAN HYPERWAR. Who will win this colossal planetary war? Who shoved the bottle up the ass that broke the Proto-Finnic Holy Roman Khaganate's back?
