Which Peanuts character am I?

Rerun
Good grief! Rerun was one of the last characters to join the Peanuts gang, and like him you are surprisingly gifted and precocious, but also work hard to make sure your goals are met. Rerun is the youngest Peanut, and like him you still often don't get your way even when you know better.

United Feature Syndicate says:

Rerun Van Pelt is often mistaken for Linus even though he's his little brother. He can always be recognized in his trademark overalls. Rerun is more skeptical than his brother, much harder to convince, and always gets around Lucy where Linus gives in. His only fear is being the passenger on one of his mother's bicycle-riding errands. Somehow, Rerun is the only witness to her riding into grates and potholes. Luckily, he always wears a helmet. Rerun also longs for a dog of his own, but since his parent won't let him have one, he tries to "borrow" Snoopy from Charlie Brown. Snoopy won't have any part of it unless Rerun brings cookies.
