In HS I saw a guy who was playing raquetball in the gym and the ball hit him and sucked his eyeball out of the socket. When he looked at you his eye would track even though you could see all the muscles etc moving it around, FREAKY. He was OK the hospital just poped it back in and he was quite sore from having all those muscles stretched.
I was also first on a accident and when I got to the car I looked in the passenger window and cause he had his window partially rolled down he smacked it when he was going sideways and I could see his skull.
It was a gash about 5" long and 1 1/2 " wide not very much blood just bone peaking through.
