David Letterman Is on Track to Break Johnny Carson’s Late Night Endurance Record

By

Jeez Louise. It looks like David Letterman is going to make a deal to stay on the air until 2014, which would mean he’d been hosting a late night show for 32 years. After 11 years at NBC, he’s closing in on 20 at CBS hosting The Late Show. 32 years would beat Johnny Carson’s 30-year record on The Tonight Show at NBC, and it would also beat the record for Amount of Time Humans Can Do Any One Job Without Going Completely Insane. So that’ll be fun to watch.
