I have downloaded everything interesting from YouTube. It's hard to choose the favorites. Let's say, I keep them in categories "accidents", "oobleck", "mud fun", "fetish video", "educational". The "accidents" folder has 7.5 GB of video, the "mud fun" - 3.5 GB. Of course, the boundary between the "accidents" and the "mud fun" is pretty fuzzy, so I constantly review and rearrange the collection. My preferences change with time, season, weather and mood, so my choice of the most favorite videos also change.
Currently,
the best from "mud fun"
