Working on the car.
When I was a kid dad had to work on the car. The transmission messed up so he decided he was going to fix it his self. So he was in the front yard at Granny's house trying to figure out how to get it the transmission in. While under the car with the transmission up in the car, he lost his hold on it and it fell out onto his head. He got it off him and crawled out from under the car and flopped onto Granny's porch with blood coming out every part of his face and popped his eye ball down in his cheek.
He cracked his head and every time he sneezed he had to hold his eye in, or he could hold his nose and blow and his eye would jump up and down. It was so funny.
