While plenty of online videos're just a waste of time, others can be truly informative: you can discover truly interesting things like how to muddle mint, and LEEEEEEROOOOY JENNNNNNNNNNKINS! For a catalog of clips that'll learn you good, hit PupilTube.

Developed by a Dutch econ student after he realized the Internetz could teach him more about his subject than textbooks could, Pupil's a hundreds-strong compilation of vetted-for-quality how-to vids and tutorials from across the Web, tackling subjects from finance to self defense, but sadly, none on how to procure cheeseburgers for cats who've just learned they can haz them. Categories range from Sports & Vehicles, to Food & Drink, to Music and Entertainment, with each how-to clip (from YouTube joints to vids from advice-specific sites like MonkeySee) getting an out-of-5-star user rating informing helpfulness, plus a button to save it to your favorites, so you're not late for work each day searching for that one on how to tie your shoes. Choice tutorials include a comprehensive 7-minute piece on how to brew your own beer hosted by a suds-loving Scottish dude, relationship advice like how to get your girlfriend into video games as explained by a Playboy Playmate, and the most basic of life skills: how to drift your car using the e-brake, taught and demo'd by a retired Japanese pro driver known as the "Drift King", who is also the mortal enemy of Mr. Plow.

If you find a video somewhere else that might be a good fit for Pupil, you can upload it, and if it's deemed legit & helpful by the site's team they'll keep it up there, especially if it teaches how to make geeky multiplayer video games fun, by getting high and screaming your name like you mean it.
