What happens when an eight-year-old mischievous boy genius becomes best friends with the brilliant-though-humble elementary school janitor? Pages upon pages of hilarious comic strips, of course! Caulfield gets a kick out of frustrating his mean old third-grade teacher, Mrs. Olsen, by cracking wise-guy jokes and facetious questions; his reward is detention, where he gets to spend time with the equally quick-witted janitor Frazz. The two spend conversations discussing everything from math to literature with funny insight accessible to readers of all ages.
