(This topic assumes you have seen at least one episode of The Regular Show)
For unspecified reasons, you have to work at The Park for a day. Because of more unspecified reasons, you have to work with either Mordecai or Rigby, but not both or neither. For the most part, you will be doing manual labor, ranging from changing lightbulbs to mowing fields. Occasionally, you will be given a more tedious task, such as ridding the computer of a virus or retrieving a prized possession from the plumbing.
If you are unlucky/lucky enough, you may have an improvisational battle with a peculiar group of ne'er-do-wells.
Who do you choose to work with, and why?
I would choose to work with Mordecai for a day.
He doesn't throw caution to the wind, and understands the importance of getting the job done. Also, he seems like a pretty chill guy.
