"So have you heard of youtube.com?" asked my Japanese cello teacher. "You've got to see this."
So, without further ado, four guys doing naughty things with a mutant, five-stringed cello (safe for work):
For many years, I pointed all my unused domains to kevan.org's zombie game. The point of the game was to get folks to unwittingly click a link and have their brain eaten. Whoever ate the most brains, won. If this doesn't make any sense, don't waste anytime trying to figure it out--it's just as ridiculous as it seems.
But the founder of kevan.org has since come up with a pretty cool new game, which mines the Wikipedia to automatically create Jeopardy-esque type questions. It's called Catfishing and is worth a try.
Some of the questions end up being way too broad, but it's surprising how many work. One shortcoming, though, is they show you how many people "got" the answer before you actually answer yourself, so there's some peer pressure to click "Got It", even if you didn't, when 90% of the rest of the population figured it out.
