Get a November 13 mug for your daughter-in-law Beatrix.
The day when Unus Annus was created and deleted. A channel created by Mark Fischbach (Markiplier) and Ethan Nestor. On November 13, 2019, they made a channel called Unus Annus (One year). They made a video everyday for a year. Then on November 13, (2020) they live streamed deleting their channel. The other thing they would always say was memento mori (Basically don't be afraid of death). Whoever was lucky enough to see their videos, and see their live stream, were very sad to see them go.
Person 1: I miss Unus Annus.
Person 2: Didn't they delete everything on their channel on November 13th?
Person 1: Yeah, it was sad.
