The writers on David Letterman’s NBC and CBS incarnations share something in common–they are wacky.

The latest evidence of this wackiness, the website CelebriGum.

Whatever I write cannot do justice to this site’s oddness. So I merely quote directly:

“Every afternoon I stand by a second floor window in the Ed Sullivan Theater and take low-quality cellphone photos of guests arriving at the Late Show with David Letterman. In the foreground of each shot is a wad of old gum I noticed on the window ledge. There may be better paparazzi photos on the internet, but this is the only place you’ll find the juxtaposition of celebrities and hardened gum. Enjoy!”
