When I was attending university I would judge the HS debate tournaments which were occasionally held on campus. One weekend I decided to have some fun so I dressed extremely casually, t-shirt and shorts with torn sneakers, then sat a few rows back from the front of the podium.

When the HS debaters came in and saw me there, almost to a person they rolled their eyes or silently sneered, believing me to just be some dumb student who wandered in...when time came to start and I sat up and asked everyone to write their names on the blackboard, and they realized I was the judge, the looks on their faces were priceless.
