The Adventures of Jimmy Neutron: Boy Genius, Season 1

Carl:
Look! There's Jimmy's entire memory of the 3rd grade.

Sheen:
And we drag that to the Jimmy side. "Supreme dislike of show-offy boys."

Libby:
That's Cindy. Oh, yeah.

[Later…]

Carl:
[tiredly] "Ability to whistle." Can Cindy whistle?

Libby:
I don't know.

Sheen:
We gave Jimmy rapturous enjoyment of mustard. Let's give Cindy whistling.

[Much, much later…]

Carl:
Let's see... "Extreme dislike of girls who dislike boys who dislike girls who dislike show-offy boys who dislike pedantic show-offy girls who dislike..."

Sheen:
SO CONFUSING! TOO MUCH WORDS!! Just throw that one away already! [The memory with the words "Extreme dislike of girls who dislike boys who dislike girls who dislike show-offy boys who dislike pedantic show-offy girls who dislike..." is deleted] And download.
