I may have you beat -

While @ GT I was a part of "Connect with Tech" for a year - basically you let high schoolers who think they want to come to GT go to class with you for a day. The lady who ran the program was named Carol Heller. I had to call her one day for some reason and got her voicemail, so I started "Hey Hellen Keller, this is ....oh shit...oh shit, uhm...(pause)...uhm...hang up." Roomate was also there to hear it and was rolling in the floor.
