Well, he might not be a professor, but Dr Mike Clifford is the first to admit he's unconventional.
In an attempt to make his lectures more entertaining, Mike has taken to dressing up in different outfits.
For my first meeting (17 October 2007) he was dressed as Isambard Kingdom Brunel (click here for video).
But as these pictures show, he sometimes goes for something a bit crazier. And he's started taking acting lessons to improve his performances!
