While rooting around YouTube, I found this outtake. I also have it on a blooper compilation videotape that I got when I was younger.
To this day, it still makes me laugh. Draw your own conclusions about my level of maturity (or lack thereof).
Note: This clip contains one mildly inappropriate word (that I utter roughly a kajillion times during the course of a day, without much provocation) so view at your own peril!
