Everyone is on the internet, and there's no saying for sure who is going to see what you're saying. Because of this, you have to be careful of what you say, and to who, especially when throwing out "facts" and criticism. The person you're targeting might just have a little more info than you do, or they may actually be the person you're talking about. It's embarrassing and somewhat humbling when it happens, but it's especially funny when someone doesn't recognize a popular celebrity or other big name, humiliating themselves for all to see. Maybe do some extra research before telling someone they're wrong about something.

Don't you know who I am is a popular sub on Reddit where users collect and compile screenshots of moments where someone wrongly corrected someone, or just didn't realize who they were talking to. Resulting in a humbling "don't you know who I am?" from the targeted person. Here are 20 recorded times this has happened online.
