Haha! I've used QI as justification to my family that I can continue to crack my knuckles. It doesn't cause arthritis, Stephen Fry said so.
Indeed, all hail QI xD It's a much more fun show to follow as a Canadian, since nobody else here has seen it, so when I use trout I learned on it the reaction I get is "HOLY trout YOU'RE A GENIUS" and not "Yes, I watch QI too, you pompous drool." I have won *so* many free beers in wagers because of that show.
