The Late Show With David Letterman

You don’t have to wait until later tonight to begin saying goodbye to David Letterman (though if you’re like us, you’ve already started that process) — you can do it right now. The venerable, longtime Late Show host is ending his 33-year run with tonight’s episode, which promises to be a fantastic, hilarious and appropriately heartwarming sendoff. But before we get to that, you can watch Letterman’s final Late Show entrance right now.

Love him or hate him, its hard' not to respect Norm Macdonald for how he handled his last appearance on The Late Show With David Letterman. With Dave's last show coming up in a few days, Norm used his stage time to give thanks for everything Dave did for his career, as well as just being a great influence.

Although we understand that 'The Late Show' will be getting a bit of a makeover when long-time host David Letterman exits later this year, and while we're extremely excited that Stephen Colbert is taking over the post, we still have a teensy idea: maybe Bill Murray could host it? Or just appear on every single episode? Does Colbert need a sidekick? He has to, right?

Whoever is in charge of scheduling over at Disney (we imagine it's many people, but just go with it) is going to be in a lot of trouble when they realize that they've put their next 'Star Wars' movie up against 'The Nest,' an adult comedy starring Tina Fey and Amy Poehler. How do you even compete with that? You don't. Just pack it up now, J.J. Abrams. You're going to lose this box office battle.

Well, that was fast! Just one week after David Letterman dropped the 'Late Show' bombshell that he would retire in 2015, his replacement has officially been announced. Following early and decisive rumors, Stephen Colbert will officially leave behind Comedy Central's 'Colbert Report' to ascend the late-night throne as the new host of CBS' 'The Late Show.' You're welcome, nation!

Are you looking to live a long and healthy life? If so, you might want to take some advice from Betty White, who, at age 89, is still going strong. Last night, the Emmy-winning TV legend appeared on 'The Late Show With David Letterman,' during which she revealed her own tips on how to make it to your golden years.
