Owwww

Can you get a goose egg on your knee?  I've heard of getting a goose egg on your head, but I don't know if it is possible to get a goose egg on your knee.  If you can then I have one and I'm getting no sympathy from my family.  It was even my brothers truck that gave it to me and all he does is give me a hard time.  He keeps offering to whack my now swollen knee with a hard bound book to see if it will "pop" the swolleness.  He swears he would only whack it once unless he likes it.  Sooo much sympathy coming my way.
