Only ANNUS-es May Watch This Video

Summary
Mark and Ethan compete against each other to see who would amass greater viewership on their channel within the next 24 hours. To participate, the audience had to simply choose to watch one of the two videos that represented each character; Ethan representing Unus and Mark representing Annus. To showcase additional support, viewers on either side could purchase their distinct merchandise or brandish each character's spiral pattern as their user icons; Ethan's Unus spiral would emerge from the upper left corner, while Mark's Annus spiral emerged from the lower left. Both videos contained a series of green screen gags that would later be repurposed by Unus Annus fans to create memes, some of which were showcased on the channel at a later date. Mark ends his video with "Annus Annus", instead of their usual "Memento mori, Unus Annus". Both videos were uploaded on the same day, side by side. The winner was announced the following day.

Trivia

 * The inner circles of the episode's number, 169, on the video's title card read "DUDE!" and "NICE!", referring to the number 69 being a so-called "sex number". This also paralleled the one from Ethan's Unus video that read "BRUH!" and "SWEET!".
 * Although they're treated as part of the same segment, this is the only time the two uploaded more than one video in a single day.
