Beaver's best pals included apple-munching Larry Mondello, Hubert "Whitey" Whitney, and the old fireman, Gus. Except for Gus, Beaver's friends steer him into trouble time and again.
Judy Hensler was Beaver's snitching, goody-goody classroom nemesis on the show. Benjie Bellamy and Chuckie Murdock were both small boys and Cleaver neighbors who caused trouble.
Beaver had two female teachers, Miss Canfield and Miss Landers. Mrs. Rayburn was the principal of Grant Ave. Grammar School.
Wally's closest friends were wise-guy Eddie Haskell, Clarence "Lumpy" Rutherford, Tooey Brown and Chester Anderson.
