I haven't heard of this show "Principle's Office" but if this clip is indicative of what I'm missing out on I might try and tune in.
The principle of a high school calls in two seniors to talk to them about "dirty dancing" also known as "grinding."
The two students flip the conversation on him and basically make the principle look like a douche. Whether it is scripted or not it is hard to say, but it's still kind of funny. Plus hearing people with mid-western accents say "griiiiinnnndddddiiinnnngggg" is funny I don't care who you are.
