So reports Daniel W. Drezner (on the adultery part) and Professor Chaos (in regards to the cars).

In regards to the differences between real professors and their fictional counterparts, we have the money quote from Mrs. Drezner:

“The reason professors sleep with their students in fiction is because any realistic portrayal of your jobs would bore readers out of their skulls within ten minutes.”

Indeed.

(And Dan’s daily schedule sounds familiar, although I call foul on the notion that he only surfs news sites from 9:10 to 9:30).

h/t to James Joyner for the Drezner post.
