There had been many parodies of What's My Line? through the years.
One of which, What's My Crime?, was shown in the 1961 Disney film, 101 Dalmatians.
Another one, Guess My Line?, was mentioned, but not seen, in an episode of The Flintstones.
But perhaps the most famous parody of What's My Line? aired during the first two seasons of Sesame Street.
This parody, known as What's My Part?, was played the same as What's My Line?, except that only the Mystery Guest portion was played, and the challenger was a part of the human body.
The host of course was the Bill Cullen of Sesame Street, Guy Smiley! (#9 on TV Guide's list of Top 10 game show hosts!
