I'm sorry for your injury but the mental image made me laugh.
McDonalds fries are decent but I like fries that taste more like potato with the skin on them. We have a chain called Johnie's Charcoal Broiler in Oklahoma City that make awesome potato-y fries and they also make excellent onion rings.
It's cool, and it's funny now that I look back on it, but it hurt like hell. I'm sorry I didn't immediately drive to a lawyer. If people can sue McDonalds for coffee injuries etc I probably could have done the same for sharp fries.
