LOL...that's hilarious. But I agree, how did they not notice this???? Or maybe they did...what would a kid think anyway?
I think kid-show writers always try to keep the adults amused.
A few years ago when the Power Puff Girls were popular there was an
episode where the villains were called the Beat-Alls and every line was a quote
from a Beatles' song. Now what little kid would know that? Some of the songs were so relatively obscure even the younger parents wouldn't have known them.
