What Does the "G" Stand For?

No lie, I saw this on Good Morning America the other day:

What does the "G" on the Green Bay Packers' helmets stand for?

'Many people think that it stands for Green Bay but it actually stands for "Greatness!" The logo was created in 1961 by Packers equipment manager George "Dad" Braisher.'

(Straight from Google)

Go Packers!
