About
MEM primarily makes comedy videos ranging from 2–5 minutes long. Most of their videos are parodies of "How to" videos, such as How to Procrastinate, that are done in a ridiculous fashion.
By far their most famous video is How Animals Eat Their Food, which consists of a man preforming impressions of different animals eating food for his friend. A sequel, labeled How Animals Eat Their Food Part 2, was released about a year later, and included multiple other YouTubers, such as Harley Morenstein, PrankvsPrank, and Rhett & Link.
MEM also has a second channel labeled MisterEpicMann2, which contains bloopers from their videos.
