ROFL!! Ahh, good old Mr. Potato Head. I remember when I was a kid in the 50's, having one of them...and a Cootie game as well. Thankfully, some things like Mr. and Mrs. Potato Head, and the movie "A Christmas Story" haven't yet been banned.
Then you must have used a REAL potato!
I know a potatoe was quite deadly for Dan Quayle
