8. Baby Talk
This may sound like it would be the most annoying class on campus at any college, that is if any self-respecting university would allow such a pointless class to be taught, but at Greendale Community College it is a thing. In an episode where the study group explains how normal or odd Greendale is, they present examples of the class choices, one of which being Baby Talk. So what do you do in Baby Talk? Exactly what it sounds like, a grown adult teaches you to talk like a baby. It seems simple enough. The linguistics behind the communication of an infant cannot be that much of a headache. I'm sure Baby Talk will come in handy in the eventual uprising of baby overlords when their demands must be met. Then your baby talking skills will possibly allow you to be a pet of theirs at best instead in a prison in their diaper dungeons.
