Tina Fey and Amy Poehler

Tina Fey and Amy Poehler are undeniably two of the funniest personalities in show business, but what many people don't know is that they've been close friends since the early '90s. Their enigmatic friendship began to take hold of the public in 2001 when they both landed roles on Saturday Night Live, and since then, they've appeared on the cover of Vanity Fair and Entertainment Weekly together, acted in films together, and set a standard as hosts of the Golden Globes that no human stands a chance at meeting. We can only imagine the shenanigans they get up to off screen.
