Wow, 776 takes since the reset and 24.4% of test takers got 20/20. I expect that will go down... although to be fair the Silverdome question is the only really challenging one, in my opinion.
True. While Americans certainly engage in this sort of thing, most data would suggest that American workers are much more industrious than average. Perhaps it was an American who coined the term?
According to Merriam-Webster, the term originated from an American con in the 1800s where someone would paint a brick of some cheap metal with gold paint and sell it as an actual brick of gold. By WWI, the term was used in the US Army to refer to someone who was slacking off but made it look like they were working, or for someone who made it look like they had a valid reason for not working (like faking sick, say.) So, near as I can tell, the connection is just that it's a term that originated in the US and is still primarily used there.
What really surprised me, was this:
I don't know anything about baseball or even where it is played outside the USA, but in a single weak attempt I typed in "Toronto".
Well, it didn't count since that is not the full name of the club, but still...
