Hunting HeeHoo

Summary
Continuing from the previous episode, Mark, now dubbed Neanderthalensis Marconius or HeeHoo after supposedly devolving into a primitive, is loose in the wilderness. Three months later, Ethan comes back with a film crew to make a documentary about Mark's condition, while attempting to locate the individual.

Rummaging through the woods where Camp Unus Annus once stood, Ethan locates Mark in the distance and calls out to him, as Fischbach proceeds to run away. Returning to the cabin, the crew hears something in the distance. Rushing over to investigate, they discover Mark entangled in a rope. Ethan attempts to communicate with him one final time, but to no avail. Approaching closer, Mark lunges at Ethan before being gunned down with tranquilizers. Recovering from the shock, Ethan picks up Mark's unconscious body and walks away into the distance.

The finale of the episode is accompanied by a variety of info cards that read: "After 6 months of rehabilitation, Mark was finally able to return to YouTube. Ethan went on to defeat Joey Chestnut in the 2021 National Hotdog Eating Championships. He ate 102 hot dogs in 10 minutes. Ethan was rushed to the nearby Norbert Moses Memorial Hospital to have his stomach pumped. There he would meet the love of his life, Michelle Obama, who had also been hospitalized for a hot dog-related injury. Together Ethan and Michelle shared a common mission. They toured the country, warning future generations about the dangers of processed foods.

''After a messy separation that left their 47 foster racoons fatherless, Ethan decided to return to his roots. He and his new business partner, Benjamin Ketchup, founder a specialty foods corporation focused on "mystery meat" sausages and their accompanying condiment, Mystery Mayo™. This small mom-and-pop shop quickly grew into a ruthless global empire, decimating all other processed meat competitors on the market.''

''That winter, disaster struck. What we now know as The Great Bovine Befuddle of 2020 left every farm animal on the planet a genetic hodge-podge of their former selves. In a brave new world dominated by mystery meat, Ethan was King. Exactly six meat-months and one dairy-day after the advent of our new calendar, the Unus Annual... Mark regressed. Ethan was tragically ripped to pieces as Mark bashed him to death with his own kneecaps. The world rejoiced the death of their fallen tyrant. This program is dedicated to Ethan "The Meat Man" Nestor, 1996 - 2020."''
