Quite recently I’ve been watching some of the original American What’s My Line TV shows and this one is fantastic. It features Doris Day as the ‘mystery’ guest and the panellists have to ask her questions, which she answers in strange sounds to disguise her identity and they have to guess who she is.
This is the longest clip I’ve uploaded, it’s nearly half an hour long, but a great reveal at the end. Enjoy. If you do, there are many more clips of that show available and one of the greatest ‘mystery’ guests was Walt Disney.
