I first watched this video over 15 years ago when my oldest was a baby.  Now, 15 years later I am still singing the song to my 4 year old.  Of course, she has never seen it, she has only heard us singing it.  Well, thank God for the internet.  I found the video on YouTube and decided to share it here.  I also found that this was updated with Ernie and Elmo.   I am posting both versions here.  This is definitely a favorite of ours to sing.  My kids love to be the echo.  Enjoy. I have loved Sesame Street since I was a kid and I loved it all over again when I had kids.
