My first ten minute as a lab instructor in a full intro to computing class. I was standing talking and backed up a bit stepping on the leg of my swivel chair. I fell right on my ass hard. Cracked a joke but the whole class of about forty students didn't laugh or say a word. Was rough and I was showing some code at the time and I blame this on the code to this day.
