The Origins of “Bazinga!”
“Bazinga” is a term that was coined by a writer on the show named Stephen Engel. He loved playing pranks on his co-workers. On one such occasion, he hollowed out a grapefruit, strategically put it back together, then gave it to the show’s co-creator, Bill Prady. When Prady tried to eat it, Engel yelled “Bazinga” as it fell apart.
