Convention of blondes

- At a convention of blones, a speaker insisted that "dumb blonde" myth is all wrong. To prove it he asked one cute young volunteer, "How much is 101 plus 20?"
The blonde answered, "120."
"No," he said, "that's not right."
The audience called out, "Give her another chance."
So the speaker asked the blonde, "How much is 10 plus 13?"
Slowly the blonde replied, "16."
"Sorry," he said, shaking his head. Once again the crowd roared, "Give her another chance."
"This is your last try," warned the speaker. "How much is 2 plus 2?"
Carefully she ventured, "Four?"
And the crowd yelled, "Give her another chance!"
