It was parents' day at the local university. The Dean was showing a group of parents around the campus. While they were walking by the Science building, a student ran out dressed entirely in black, wearing a mask and brandishing a sword.
One parent inquired about what she had just seen. "Wouldn't someone running around dressed like that be a distraction to the other students?" she asked the Dean.
"Well, yes," the Dean replied, "But at this school we have a Zorro Tolerance policy."
