Who is Yehudi, and what exactly does he do? In the 1930s on Bob Hope’s radio show there was a musical guest named Yehudi Menuhin. His name proved so catchy, along with sidekick Jerry Colonna’s joking phrase, “Who’s Yehudi?” that it entered the common vernacular, coming to refer to anyone, or anything, mysterious. Yehudi is, for example, the little man that turns on the light inside the refrigerator. He holds up strapless dresses. The Navy even had a secret project named Project Yehudi. It’s sometimes spelled “yahootie.” This is part of a complete episode.
