I am fortunate in the sense that I teach video game development. Fortunate that I work in an industry that is fun and interesting for the students (well ok... for me too).
But the time I tried a guest lecturer ran into a bit of a snag for me. The friend that I had log in happened to be the "hero" of the gaming world for some of the students and it was very tough for me to hold them back from sounding like Chris Farley on SNL asking them things like:
"Hey ... remember that game ? Yeah that was cool"
