4. Youth Tar Apocalypse
Recalling the age-reducing tar from an earlier episode that among other things caused Zoidberg to revert to a larval form, Bender hits upon a get rich quick scheme. Playing upon human vanity and dreaming of all the booze he could ever desire at his metal finger tips, everybody's favourite morally bankrupt robot releases vast quantities of the stuff into the environment. However, he can't stop the flow and the entire population of the planet is reduced to mewling infants. Bender is left pushing the baby carriage, much to his bemusement.
