Danny made several appearances (6 according to Internet Movie Database) on the TV
show, What's My Line? as a mystery guest. Three panelists, with masks over their
eyes, had to figure out who the mystery guest was by asking questions and receiving
answers from the mystery guest. Mostof Danny's appearances can be found on YouTube
-October 16, 1960 , November 5, 1961, March 24, 1963, October 24, 1965 and October
2, 1966. Sometimes he went on as a lying mystery guest, which really threw the panelists
for a loop. At times, Danny attempted to lie, but John Daly, the host, wouldn't let
him making for some hilarious moments and some hilarious faces from Danny.
