Looks like the new teen craze is not the selfie or the duckface. It's now the "put your phone in your own mouth". I'm waiting to see if any teenager asks his/her parents for an additional phone to take a selfie with.
It begs the question: why would your head get stuck in a trash can in the first place? Anyway, I hope they place a big sign with a head jamming warning near this trash can. And probably this guy's picture just for reference.
