Every weekday, I drive to work and I hear on the radio a selection of jokes from the previous night's Tonight Show with Jay Leno monologue.
I gotta say that, based on these daily comedy bits, there are some comedy writers out in LA who are making some pretty easy coin.
In terms of quality of content, I kinda equate The Tonight Show with the Air Farce: both are shows designed to appeal to The Greatest Common Denominator and/or grandmothers. Very safe comedy. Read: boring. It's greatest sin is that it tries to trick us into thinking it's comedy-on-the-edge. The sad thing is that so many people fall for the trick. It's not on-the-edge. It's repetitive and simple and mean. I like comedy that's mean, but to me, mean comedy must also be smart. Jay Leno jokes are not smart.
