... a survey was done on political jokes done by Letterman and Leno. 286 jokes were at the expenses of one party while only 42 jokes were made of the other party.

Unfortunately, being on a train and reading over a fellow commuter's shoulder, I was not able to read which party was skewered for 286 jokes, Dems or Reps?

Since the late night host have done their best to be fair, I couldn't even hazard a guess (wink, wink)
