July 19 - Mr. Meeseeks

“I'm Mr. Meeseeks! Look at me!”

~ Mr. Meeseeks' catchphrase

Meeseeks are an entity introduced in the Rick & Morty cartoon "Meeseeks and Destroy". They are spawned from a device and come into existence to fulfill a singular purpose of the person who summoned them. Once that purpose is fulfilled they disappear in a poof. From the wiki:

"Their motivation to help others comes from the fact that existence is painful to a Meeseeks, and the only way to be removed from existence is to complete the task they were called to perform. Not even physical violence is able to eliminate them."

The longer Meeseeks stay alive, the worse they off they become as they struggle to fulfill their purpose. Hilarity ensues.
