Tina and Amy give us the 'Broad City' crossover promo we always wanted

How do you improve on our two favorite comedy besties on TV? By adding our two favorite comedy besties in movies.

Tina Fey and Amy Poehler joined the Broad City in a crossover promo for Sisters that had us seeing the light. Poehler had guest-starred on the Comedy Central series before, but this is the first time she and Fey had joined forces with Abbi Jacobsen and Ilana Glazer in such a holy union.

The promo has two "bad" sisters (Abbi and Ilana) who get assigned two religious sisters (Fey and Poehler) in their rehabilitation. NSFW jokes and feminist humor abound.

We're not sure if it's an ad for Broad City or Sisters, but we'll take it as both. Or for an imaginary movie featuring all four sisters in one. Please? We disagree with your assertion that "people don't want to see that many women talking at once," Tina. Give this to us.
