Three blondes are undergoing a maths test. The examiner asks the first blonde, "What is 4 x 4?" To which the blonde replies, "36." He asks the second blonde, What is 4 x 4?" To which the second one replies "Saturday".
Shaking his head he asks the third blonde, "What is 4 x 4?" The third blonde replies, "16."
"Very good," said the examiner. "Now tell those other two how you reached that conclusion."
"Easy," she said, "I just subtracted Saturday from 36."
