Charlie Brown is the main character in the comic strip, Peanuts.
Snoopy often lies on top of his doghouse and sleeps, sometimes all day long. In one strip, Charlie Brown refers to him as a hunting dog, because he always hunts for the easy way out of life. In later strips, Snoopy's main human contact (when not indulging in his fantasy life) is with Rerun van Pelt.
