What would it mean to fall for it?
Are the links themselves dangerous?

It is sadistic, kids are sadistic.
I believe this Vsauce video explains the phenomenon I mean (I have not watched the video and can’t right now).

It’s not like that, it’s a game for kids, when there is a yellow car you say “yellow car!” and you can punch someone on the shoulder, but only the first who sees it can do it.
Do know this thing about the two yellows? There is pure yellow and mixed yellow, both look yellow.

You only like it because you can hit people? You know that game?
Yellow is difficult, I think :D

What is your favorite color on a car?
