'What's my Line?' is a family game show which ran from 1950-1967.
In the show, contestants with unusual occupations were interviewed by a panel. The panel were only able to ask closed questions which could be answered with a "yes" or "no".
There was also a 'mystery guest' (usually a celebrity). The mystery guest usually disguised their voice, and the panelists were required to wear a blindfold when questioning the mystery guest.
Gene Kelly appeared as a mystery guest in two episodes:
- 23 June 1957
- 27 December 1964
