Justin Bieber gave some lucky fans a DNA sample when he uncorked a sneeze during his concert in Finland.
Justin was doing his hit, "What Do You Mean?" ... when the countdown started on his snot rocket launch. Y'know how it is when you just can't hold back. Check out the video, which shows a juicy projectile going straight from JB's schnoz to the not-at-all cheap seats.
For Justin, but more for the fan who took the hit.
