It was very interesting to see how comedians deal with this inside joke and how it seems to have a life of its own. The joke itself is, admittedly, pretty lame. It's what has been done to it over the years by the different comics, that makes the story. It's fascinating to see how something can live so long through metamorphosis. I laughed until I couldn't breath watching Billy the Mime, as I have never laughed at a mime at all before. By the end I was beginning to see why so many comics found this so amusing and how sometimes we just need to lighten up in life because some things are so over the top that you simply can't take them seriously. Not for the politically-correct...but then...is anything?
