Regular Show was one of those shows that when I saw the previews, and thought "What is wrong with kids shows these days..."
Then I watched an episode one day while sitting at home, "Weekend at Benson's" The 1980s kid in me beamed up and said, "No.... It can't be..." followed by them knocking out Benson, putting sunglasses on him, and acting like he is awake. "Oh man they totally did..." My inner child smiled from ear to ear remembering those nights I stayed up watching "Weekend at Bernies." and those memories combined with the cartoon hooked me so hard.
After that I watched every episode and loved every minute of it. I read up on the creator and found out he is only 3 months older then me and both grew up in California. We probably had pretty similar childhoods, which may explain why I get the references and humor so well.
