There was a young man named Dennis
Who greatly enjoyed playing tennis
But one day had to stop
In his leg heard a 'pop'
Felt to continue, to his health, would be a menace
Because of the pain it did bring
Dennis knew he must take care of this thing
Needed to do something fast
Or the pain, it would last
So he checked his insurance plans MD listing
He saw Dr Moshe Goldstein
Who said 'Many times, what you have, I have seen
Dennis, here's the thing
You pulled your hamstring
With proper treatment, you'll return to the way you been'
'But listen, Dennis, to me, Dr Moshe
What I say, hope you won't lose your composure
As an observant Jew
I'm forbidden to treat you
You know that a hamstring's not kosher!'
