And trust me there are a few other songs he ‘butchered’ for me as well. I decided to be kind to you and only ruin Jingle Bells for you and not any of the others. ;-)
Just before posting this I remembered something from my teenage years…
Jingle Bells
Batman Smells
Robin laid an egg… 
That’s all I remember.   And I believe that must be almost as bad as the ‘slaying’ of Jingle Bells.  I love the Holiday Season!
