I felt this episode was one of the most entertaining I had watched in a long time and is probably destined to be one of my all time favourites.
However, I was truly disappointed when John didn't show a bit of good sportsmanship and go along with doing the twist. Don't get me wrong, I love and respect John dearly and cherish his memory, but I think just this once he could have been a little less of a stuffed shirt and gone for it for the entertainment value.
And how about that somewhat risque comment John made about "only doing the twist in his bedroom"! Hmmm.
