it still makes me laugh

I just finished watching the Carol Burnett 50th Anniversary Special and I am amazed at how many times I laughed. All of the sketches were ones I had seen before but they still made me laugh.  The ones involving Tim Conway were the best.  Most epic were the Siamese elephants bit (they were joined at the trunks), the dentist, the slippery doorknob, and of course Carol's own scene in "Went with the Wind" where she appears wearing a dress made from draperies with the curtain rod still attached. And all that comedy without any obscenities or crude innuendos. Isn't it interesting that good, clean humor could be so funny? Some current writers of 'comedy' shows could take notes.
