I haven't challenged you guys in a couple weeks but I'm back with a good one. Every year at this time the media talks about Black Friday and describes it as the biggest shopping day of the year. But, as Snopes points out, this is a myth. It's frequently not even in the top 5 shopping days in terms of dollars spent. So, this got me thinking about myths, misconceptions, urban legends, etc. And I'd like you guys to make us all a little smarter by sharing some that really get under your skin - or just ones you think are funny.

I'll pick my favorite on Friday. Now go, make us all a little less dumb with your crazy knowledge!
