If you haven't been following Funny or Die's Drunk History series, you're going to laugh when you see what you're missing.
Here's how it works: the producers get somebody super-drunk, then have that person tell a story from history. This story is usually completely inaccurate, but hilarious due to the aforementioned super-drunkenness. Then the producers get actors (often surprisingly high-caliber actors) to reenact the story word-for-word as told by the super-drunk person. The rest is Drunk History.
In this episode, the story (sort of) of Fredrick Douglass, as told by (drunk) Jen Kirkman, and performed by Will Ferrell, Don Cheadle, and Zooey Deschanel.
