There are a lot of stupid trends that take off online these days, so it takes a lot to actually be one of the top ten stupidest ones featured here. A great example is the duck tape challenge, which involves wrapping someone with duct tape and filming them try to escape. It sounds stupid and painful, but it also ended up being surprisingly dangerous when one kid hit his head on a window ledge while trying to escape and suffered traumatic brain damage and went blind in one eye. Not all of the selections are dangerous -some are just idiotic marketing ideas that actually worked, but in one way or another, these internet trends remind us that we live in a planet of dumbasses.
