Last night, Howard Stern appeared on the Late Show and gave David Letterman some pointers for crushing Jay Leno, like for one, don’t do commercials with him. He also told Letterman’s sidekick and producer that they need to step up their game.

I’m not even a fan of Letterman (Conan, Kimmel, Fallon, or Ferguson), but anyone contributing to the downfall of Leno is doing right by me.
