Enough folks are posting obits that I figured I'd instead post some video. Note that this is NSFW unless no one can see your screen.
The background: It was Soupy's birthday in 1959. The crew was playing a practical joke on him for his birthday by putting a stripper behind the door during his live TV show. Luckily for Soupy and his career, the version where you could see what he was seeing never got aired.
Update: YouTube yanked the original video, which included the version folks actually saw on TV. I found this on the Internet Archives.
