Linus is the Philosopher of the Peanuts neighborhood. He often gives advice to Charlie Brown to help him unravel his hang ups, even though Charlie Brown is older than him. He is not an original Peanuts character, but was brought into the series (newspaper comicstrip, not TV) early on after Lucy Van Pelt suddenly had a Baby Brother to contend with. The process was then repeated when Charlie Brown suddenly got a Baby Sister of his own. After a few years, little Sally Brown developed a crush for Linus and began calling him My Sweet Baboo. Perhaps Linus' most noticable characteristic is his frequent sitting down to suck his thumb and cuddle his Security Blanket, which he also weilds in such varied and imaginative ways that it's enough to make a Jedi give up his Lightsaber and start using a blanket.Linus is one of the most imaginative Characters in Charles Schulz's little world, surpassed only by the far out fantasies concocted by Charlie Brown's pet Beagle, Snoopy.
