Regular Show is a fitting title for a program that takes ordinary chores, such as preparing hot dogs, setting up chairs or cleaning a rain gutter and exaggerating the consequences of not performing said chores correctly. The main characters are a couple of slackers in their twenties who live only for the moment, even if that means getting fired. They constantly get into trouble due to their irresponsibility, but always manage to end up on top through some hilarious twist.

Regular Show is rated PG, not G, not Y7. Every time I read a negative review for this show, someone is whining about how Cartoon Network should feel ashamed for making such a vulgar children's program. Newsflash, just because it's a cartoon doesn't mean it's for kids. Family Guy has already proved that. There is a warning ahead of time that underage viewers require parental guidance, PG. Personally, I'd say it's about as raunchy as Ren and Stimpy or Rocko's Modern Life and Rocko was very, very raunchy, hence the deletion of certain scenes during re-runs. And who can forget Chokey Chicken, hm? If you're a grown up, give it a chance. If you're a grown up with kids who wanna watch it, consider their age and go from there. And if you do end up loving this show, you'll be telling "my mom" jokes in no time.
Can I get an "OOOOHH!" from everybody else who is addicted to this show? And remember to raise your right arm while you do it.
