Chicken knees

For the last 3 weeks I’ve been getting Orthovisc injections in my knees.  I have no cartilage in my knees and the Orthovisc helps replace that lost cartilage with a mix of cartilage and amino acids.  Let me tell you, it hurts.  HURTS.  The word acid is key.  It burns like a motha.  So 3 days every 6 months or so I’m out of commission because I can barely walk after my shots.  But a week later and I can walk so much better than I could before the shots.  So the last time I was getting my shot I asked my doctor what was in the gel?  He said “Rooster comb.”  Excuse me?  Rooster comb??  “Yeah, you know, the thing on top of a rooster’s head.”   I know what it is, but you’re saying you are injecting me with rooster comb??   He then explained that rooster combs are cartilage and since they can’t recreate human cartilage (we can put a man on the moon but can’t do this?) that the rooster comb is a good substitute.  I told him I guess it’s a good thing that I’m a Gamecock fan.
