A video going around shows a guy squaring up to a glass bottle hanging from the ceiling like he’s about to star in his own low-budget action movie. Big knife in hand, full confidence, swinging like he’s got something to prove.

Only problem? He can’t hit the bottle.

Swing after swing, just air. The bottle is basically untouched, just gently vibing there while this guy is going full ninja mode and accomplishing absolutely nothing.

And then, exactly what you think is going to happen… happens.

Instead of hitting the bottle, he clips himself. Not just anywhere either. Straight to the worst possible location. Immediate regret, immediate shock, and the kind of body language that says, “I have made a terrible, terrible decision.”

The reaction is instant. You can practically feel the pain through the screen.
