Imagine you're in high school, goofing around and chatting with your friends when your teacher breaks out the classic phrase — "you won't be able to get away with this in college!"

The image is then conjured in your mind of how college must be a time insanely rigid deadlines (no extensions EVER), uptight teachers with inflexible lateness policies, and an overwhelming mountain of coursework. And yeah, some professors are unfortunately, like that.

However, most of the time, college is more like emailing your professor a five-paragraph, carefully-worded inquiry and receiving "k — Sent from iPhone" as a response.

Twitter user @katiesmith024 kicked off a thread of professors either goofing off during their own lesson or using some uh, unusual teaching methods. Her own professor is seen standing on a desk, dancing and jamming on the ol' tambourine to "End of The Line" by Traveling Wilburys. What was his original lesson again? Who cares!

These professors are too chill for their own good. Here are our favorites.
