"We were driving and George stopped the car and said, 'Now look at the billboard.' It was a national campaign for McDonald‘s - 'Guess' which was very big on the left side, and small along the billboard, 'What is in a new Big Mac?' and then a picture of the new hamburger. The 'Guess' was gigantic and the rest was all small. George said, 'This is where I found the name.' We said, 'But it ‘s a hamburger.' He said, 'I love the name.' Then Maurice said, 'Okay, if you use Guess, grammatically you have to put a question mark.' Maurice put the question mark and designed the triangle."
