When I was growing up, one of the Christmas traditions I remember is of my dad reading "Twas The Night Before Christmas" in front of the fireplace.

In fact, it's something he still does... Just with his grand kids now!

So, when I came across this video, it made me smile!

Maybe you've heard the work of Jim Meskimen on Whose Line Is It Anyway, Jib Jab, or Our Lips Are Sealed.

He's known for his celebrity impersonations. Well, mainly for his George W. Bush impersonation.

After watching the video though, I have to say that his Robin Williams is almost dead-on!

Watch and enjoy:
