Charlie Brown is a character in Charles M. Schulz's comic strip "Peanuts."
He was first mentioned on April 25, 1994, when Nate asks Mrs. Clarke if Charlie Brown and Lucy (who was being played by Jenny) will have any makeout scenes during the upcoming "You're a Good Man, Charlie Brown" school play.
On May 14, 1997, Ellen points out that Charlie Brown has no hair while reading a "Peanuts" comic with Nate, who was trying to teach her about comics.
He later makes a physical appearance on May 27, 2000, as a tribute to Charles M. Schulz, the author of Peanuts who had died a little over 3 months before the comic was published. A lot of other comic artists did the sames, but most were sad, while the Big Nate comic was happier. This was one of the few strips where a character from another strip makes a physical appearance.
The "You're a Good Man, Charlie Brown" play was mentioned again on April 16, 2001, when Francis says that Nate was playing Snoopy and fell off of the doghouse five times, but Charlie Brown himself was not mentioned.
