Question: where did the phrase got beef come from

title: Where's the beef?
text: The phrase first came to public attention in a U.S. television commercial for the Wendy 's chain of hamburger restaurants in 1984 . In reality , the strategy behind the campaign was to distinguish competitors ( McDonald 's and Burger King ) big name hamburgers ( Big Mac and Whopper respectively ) from Wendy 's ' modest ' Single by focusing on the large bun used by the competitors and the larger beef patty in Wendy 's hamburger . In the ad , titled `` Fluffy Bun '' , actress Clara Peller receives a burger with a massive bun from a fictional competitor , which uses the slogan `` Home of the Big Bun '' . The small patty prompts Peller angrily to exclaim , `` Where 's the beef ? '' Director Joe Sedelmaier actually wanted Peller to say , `` Where is all the beef ? '' but because of emphysema , that was too hard for her .
