Protip: When talking about how someone "has no idea what you're talking about", try realizing the obvious, rather than the outlandish.
Someone tries to recall a statistic, and incorrectly remembers 20% rather than 11%. It's not some... whatever the hell you want it to be, and it doesn't change the point that was made, or the fact that it's a real and disturbing statistic.
All the protips in the world won't help this cat.
But it's so much fun to laugh at him, why would you do this!
To be funny. Made ya laugh didn't it?
