Yes. Professors hated teaching that class and always tried to pawn them off.
I remember one time, another professor came to me and asked me to teach it. I agreed, thinking nothing of it. The next day, my advisor came to me and bitched me out, talking about how I couldn't do that because of my job in his lab and allegedly, it would violate my research assistantship.
Of course, the following semester when HE got stuck teaching that course, he magically changed his tune and I was suddenly teaching it.
LOL.
