The stupidest things are the things that have nothing to do with technicalities, but the people themselves that said it...

I guess I should explain. I've heard a lot of stupid and impossible things from people, but the ones that really stick with me are the ones that don't have to do with the Internet themselves, but just things that show the true ignorance of the person that said it — often exaggerating or distorting details of the personal life so that they can impress others or feel better about themselves as if the Internet is their playing ground! It's terrible for them in the end, though, so I try not to worry about it!
