One day, a scientist set out to prove false the myth that blondes aren’t really intelligent. To prove his theory he gathered a huge convention of blondes. Among the women in the crowd, he selected one and started questioning her.
“What is 12×11?”

“120?”

“Give her another chance!” shouted the crowd.

Once more, the scientist asked, “What is 6×4?”

“25?”

“Give her another chance!” shouted the throng.

For the last time, the scientist asked, “What is 2+2?”

“4?” the blonde dared to ask.

“Give her another chance!” shouted the crowd.
