To Tell the Truth - William Hanna (1975)

In this clip from 1975, the panel (Bill Cullen, Peggy Cass, Nipsey Russell, and Kitty Carlisle) must identify William Hanna of the famed "Hanna-Barbera" duo that produced so many cartoons, including Yogi Bear, Scooby Doo, and others. Daws Butler introduces Garry and the panel as Yogi Bear. Watch for the Dick DeBartolo cameo in the end, though you may not recognize him from the outside. ;)
