Sometimes you see something so stupid, so amazingly clueless, that your brain never lets you forget it and when you're trying to fall asleep at night, you're suddenly reminded of it for no good reason.

These pics here are a pretty stellar collection of some of the dumbest things folks have seen online and in real life. When aliens discover these images in the distant future, they'll wonder how we stayed alive so long in the first place.

The reason it's so fun to laugh at other people's dumb mistakes is that we know we've been in those situations ourselves, and we're just so glad to be on the other side for once.

Be thankful something you did didn't end up in the list, and if it did, just know that next time you'll be the one having the chuckle and someone else's expense.
