Slogans

A professor was giving a lecture on company slogans in a college advertising and marketing class.

“Joe,” he asked, “which company has the slogan, ‘Come fly the friendly skies’?”

“United Airlines.” Joe answered.

“Brenda, can you tell me which company has the slogan, “I'm Lovin' It?”

Brenda answered McDonalds with no difficulty.

“Now John, Tell me who says, ‘Just do it’?”

And John answered, “Mom?”
