Charles "Charlie" Brown is the principal character of the comic strip Peanuts, syndicated in daily and Sunday newspapers in numerous countries all over the world. Depicted as a "lovable loser," Charlie Brown is one of the great American archetypes and a popular and widely recognized cartoon character. Charlie Brown is characterized as a person who frequently suffers, and as a result, is usually nervous and lacks self-confidence. He shows both pessimistic and optimistic attitudes: on some days, he is apprehensive to even go outside because his day might just be spoiled, but on others, he hopes for the best and tries as much as he can to accomplish things. He is easily recognized by his trademark zigzag patterned shirt.  Snoopy is an anthropomorphic beagle in the comic strip Peanuts by Charles M. Schulz. He can also be found in all of the Peanuts films and television specials. Since his debut on October 4, 1950, Snoopy has become one of the most recognizable and iconic characters in the comic strip and is considered more famous than Charlie Brown in some countries. The original drawings of Snoopy were inspired by Spike, one of Schulz's childhood dogs.
