There are a lot of great traditions in the world of late night. Every host has to endure the wrath of Mother Nature's cruel comedy by letting an animal crap in their lap. Every host has to invite a nutball celebrity who is guaranteed to shoot up or snort something in the green room five seconds before their interview.

But one lesser known, some would say downright boring, tradition has gone by the wayside. Maybe that's because the choices are usually something boring. There was Johnny Carson's face mug, Conan O'Brien's Eisenhower mug and some boring old mug that's so dull, they couldn't even sell it in the gift shop to tourists who would buy a bag of puke if it had the Last Call with Carson Daly logo on it.

All of that changed when CBS' Craig Ferguson revived this grand tradition by jamming a cardiac needle of adrenaline into its heart with his mug.
