Regular Show

If I could explain why this makes me laugh so hard, I would.

The characters:

Mordecai
A 23-year-old blue jay, who is best friends with Rigby. Together, Mordecai and Rigby are employed as groundskeepers at a park, but they are both lazy and rarely get their jobs done. Mordecai is more conscientious, mature and moral about his actions, but he tends to go along with Rigby's mischief as a result of rivalry. He can also get jealous at times, causing him to get angry. He once killed Rigby, but wished him back. Mordecai enjoys playing "punchies" against Rigby, knowing Rigby always loses. Mordecai has a major crush on Margaret, a red-breasted robin and waitress at the local café. He is an art school graduate. He was originally in the short film 2 in the AM PM, which was also created by Quintel.

Rigby
A 23-year-old raccoon, who is best friends with Mordecai. Rigby is eccentric, immature, and extremely mischievous, which puts him at odds with Mordecai at times. Rigby lives solely for self-gratification, which he sometimes achieves through selfish acts of lying or cheating; but consequentially, Rigby has a bad habit of getting himself and other people in trouble. In fact, many of the problems that the park employees face appear to be (mostly) Rigby's fault. Nevertheless, he is best friends with Mordecai and often relies on him for getting himself out of trouble, though there have been times where he's saved Mordecai. He has a younger brother named Don who he is jealous of due to people often mistaking him for the older brother due to Don being taller and larger. He was killed (and later revived) three times in Season 2, once by Mordecai, another time by Snowballs the Ice Monster, and once by Skips.

Mitch "Muscle Man" Sorenstein
Another groundskeeper at the park. Mitch Sorenstein (better known by his nickname "Muscle Man") is an obese, dwarfish, green-skinned man (ironic given his nickname). His behavior seems quite erratic and immature. Muscle Man believes himself to be macho and superior to everyone, constantly disrespecting Mordecai and Rigby and referring to them as "ladies". He is always cracking "My mom!" jokes (botched attempts at "Your mom!" jokes), much to the chagrin of everyone else (except his best friend High Five Ghost, who enjoys them). In the episode "Muscle Woman", his real name is revealed to be Mitch Sorenstein.
