Dear R. Knee,

Dear R. Knee,
You have really been a pain in my butt. And my back. And my legs. So, I think tomorrow I will go have you fixed. And if by chance you decide you don't want to, or can't be fixed, then I will replace you. That is a promise and a threat. Doesn't matter to me which way you take it. You will be allowed to bother me for a little while longer, but after an ample recovery time you better be straightened out. I mean literally, I'd like to be able to straighten my leg. Thanks in advance, Monica.
