I have been noticing this for months; it is not a one time, nor is it even a rare occurring thing. JOO and I both use Sporcle a fair amount, and anytime we play Six there are often 2 or 3 that we say "well, I've played this game on Sporcle." The only difference is, matching the word to the number of times it appears in a Beatles song is way harder than just choosing the top 100 and seeing where they end up (

Most of these ridiculous "almanac" questions we've been having (as we refer to them, as they seem that the question writer just flipped to a random page in the almanac) are actually directly from Sporcle (here's another you guys might remember:

The real giveaway, though, was the matching question a few weeks ago that read nearly word for word (I could be slightly off); "Match the country to the liters of beer consumed per capita in 2004:" Now, that question in and of itself it quite ridiculous (I recall missing most if not all of them), and we immediately pointed out "That's a game on Sporcle," but the fact that the question specifically was asking for the year 2004 seemed a bit strange. Well, here's why:

There really are 1 or 2 of these every single week in Six, and even having played the games on Sporcle before doesn't help, since the nature of these questions is not to match the answer to the exact amount.
