How They Really Make Drunk History on Comedy Central

Waters is serious about the educational aspect. "I'll only stop someone if they mispronounce a person's name or say a date incorrectly," he says. "I want it to be funny, but I also want people to know the real story."

The narrators don't come up with the stories themselves—which we sort of always suspected they did, seeming so passionate and all. "I send them three or four stories we've selected for the season and let them choose," Waters says. "They've got to love the story for it to be enjoyable [for the audience] to watch."

But they can pick their poison. "I always tell them to drink whatever they've never had a bad experience with," he says. "Nobody's drinking Mad Dog 20/20, you know what I mean?"

There are shooting breaks for eating, sleeping, and breathing—sometimes with help. "We have a medic on set and sometimes, if their energy is a little low, we'll give them oxygen," Waters says. "[The first time it happened] it really freaked me out when the medic said, "I need to give him oxygen." I'm like, "What the f—, is he dying?" But it makes sense. Nobody's ever had too much oxygen."

Wiki cheaters are the worst. "I can't rat anybody out, but it's happened so many times: Someone comes in and they're just reciting a Wikipedia page, instead of telling it in a way we've never heard," Waters says.

Get excited: There are some great actress cameos coming up in season three. "We're always casting based on who we think would play the historical figure in the movie about them," Waters says. "Alia Shawkat is one of my dear friends. She's one of the best who's ever been on the show—this season, she's playing Virginia Hall, the first woman in the CIA. Maya Rudolph is playing [famed cocaine dealer] Griselda Blanco—she really does look like her. And for Harriet Tubman, it had to be Octavia Spencer. I was real lucky to get her. You don't get paid a lot to do this show, not to brag. Octavia came by herself, didn't have any of her people, and stayed on set the whole time, laughing and talking to everybody—just being an Academy Award winner, moving her lips to a drunk girl."
