My all time favorite is grandma got ran over by a reindeer. It brings back a funny story of when my sons were young. They placed this song on the answering machine and added due to our loss we are unable to come to the phone right now. An elderly lady friend called and really thought we had a family loss and expressed here sympathy. I had to make the boys call her back and explain things to her.
My other all time favorite is the sounds of christmas. It is a LP album and I play it every thanksgiving night much to the horror of my family. Then I lock it up for another year or it would disappear.
