Ouch is an understatement-you may just feel physical pain yourself after checking out these photos taken just seconds before horrible things happened to the people being photographed.

From a girl who unknowingly says "cheese" for a photo while her friends freak out over her hair being on fire to a dude who is mid-air when he realizes he's about to faceplant hard on black pavement, the photos capture the perfect second before disaster hits.

One thing's for sure: the man whose face is about to be pummeled by a sledgehammer certainly had some words for his buddy who threw it after the camera stopped and it smashed his teeth out.
