Dagwood v. Dagwood
A Dagwood sandwich is a very big sandwich, named after the comic strip character, Dagwood Bumsted, who liked to make big sandwiches. An Indiana company alleges that it has operated Dagwood sandwich shops in Indiana since the 80's. A nationwide chain, Dagwood Sandwich Shops, LLC, has federal registrations. The Indiana company sued the chain in Indiana state court; the chain has now removed to federal court.
Of interest: "Dagwood Sandwich" has become a dictionary word, while King Features still syndicates "Blondie and Dagwood."
