Episode 99 contains one of the funniest dice superstitions I've ever seen.
Take all your d20s. You're a gamer, this is a reasonably hefty number. Roll them all. Take all the dice that rolled ones and roll them again. Any that rolled one again, take and insert in a container that won't let them tumble around. Now the next time you're in a situation where you absolutely can't roll a one, use one of your pre-rolled dice, because the odds of a given 20-sided die rolling the same number three times in a row are around 1 in 8,000.
Hilarious.
