As a former Children's Television Workshopper, I'm delighted by anything that goofs on Sesame Street. So I was enraptured to discover the entry for double bucky in "The New Hacker's Dictionary," containing as it does a parody of the classic Ernie number "Rubber Duckie."
(The best Sesame Street parody of all time is this article from The Onion that you've no doubt read before: "Letter D Pulls Sponsorship from Sesame Street: Noted Consonant Alienated by Controversial New Gay Muppet.")
