If you're like us and value your sleep, you probably nodded off into your Ambien dreamland before the party started on post-prime time TV. Don't worry; we've got you covered. Here's the best of what happened last night on late night.
Robert Downey Jr. showed up on "The Tonight Show," and it was basically the best thing that's ever happened to late night television. Behold, an "intense stare-down" between Robert and Jimmy Fallon, in which they both stared into the very core of our being while reciting inner monologue like "earth, air, water fire, Dominos stuffed crust pepperoni pizza. Nom nom nom nom nom nom nom." Yes, please.

Zachary Quinto paid a visit to "Late Night" and chatted about his hometown of Pittsburgh with Seth Meyers. The highlight? When he busted out his hi-larious native accent toward the end of the clip.

Anderson Cooper showed up on "The Late Show" to tell David Letterman all about his mom's hookup history with Hollywood legends. Apparently, Gloria Vanderbilt got frisky with the likes of Clarke Gable and Marlon Brando! And in related news, Anderson Cooper's still a Vanderbilt.

Jane the Virgin's Gina Rodriguez also chatted to David, and this rising star revealed that she's so terrified of the dentist that she cancelled a recent appointment and hurled herself out of a plane instead. Like, that actually happened.

Kyra Sedgwick showed up on "Jimmy Kimmel Live," where she wasted no time talking about getting high with her husband, Kevin Bacon. Turns out this guy had all kinds of reflective musings to impart on the universe while stoned –– including, "ketchup is just dessert masquerading as a condiment." So true, Kevin.

Finally, Jimmy Kimmel sent his crew to the farmer's market for a quick Q&A session with some unsuspecting randoms. The question: what's a GMO? Turns out no one has any idea. Other than the dude who realized that GMO spelled backwards is OMG, who definitely wins the internet today.
