Good grief! Is this the first time this trademark phrase has been used by a Peanuts cast member? I don't see it in my previous tags.
Lucy's personality isn't just a festering ball of evil, she has some rather weird quirks. (Fuzz? Really?) This strip helps to solidify Charlie Brown's developing role as long-suffering straight man. Schulz doesn't let him off the hook completely though; his fear of bugs at the end serves to unify his and Lucy's perspectives, showing they really aren't different.
Oh, one more thing...
WHY NOT WALK AROUND THE FUZZ?
