Have you learned anything interesting lately from watching a YouTube video, something you might not normally have learned otherwise?

For example, I had no idea horses could be playful animals. I recently stumbled across this amazing video of a horse playing with a dog, and it changed my whole outlook on them. I always thought they were kind of boring, dull animals. Sure, they’re beautiful creatures, but…I just didn’t think they had much in the personality department.

Have you similarly learned anything interesting lately from a YouTube video?

Obviously I’m not looking for standard instructional videos, or news clips. I’m talking about videos that were not made for informational purposes, but for you turned out to be very enlightening. :)
