Put This On Your List Of Things Never To Do

A video of a girl sticking her head out of a moving train and pulling back bare seconds before an oncoming train blasts by has gone viral.

At least one version of the video has been removed from YouTube because it depicts “dangerous activity”. And while the girl’s companions laugh it off–as she does–it’s pretty clear that you should always look both ways before sticking your head out of a moving vehicle. Or, you know, just don’t do it at all.
