Grabbing a Light

I've always found smoking faintly ridiculous and that might just have something to do with this skit from Bob Newhart. I was thinking of a caption for this blip when I suddenly remembered it for the first time in years. I loved that I was able to listen to it within a couple of seconds of the thought popping into my head. 

I wonder how many of you have heard it before? I suspect it may not sound so funny now to anyone coming to it for the first time, but I can remember listening to this as a kid, from an LP, sitting with my Dad and being creased up with laughter. It's one of my strongest childhood memories.
