Since I had my surgery 11 days ago, I have heard or come up with more than a few knee puns. Thought I'd share a few and see what others had heard...
"I kneed a break"
"Get down on your knees and thank God you still have a leg to stand on" (Card from my mom two days after surgery)
"Keep it elevated means the leg, not the blood alcohol level" (surprisingly, mom once again)
"Do you kneed anything?" (Any combo of need/kneed works)
I have heard a ton more but my brain is not working this morning. (it is the weekend)
