Tina Fey and Amy Poehler Join Broad City Stars for a Hilarious Mashup

Pardon us for geeking out, but the two funniest female duos in comedy -- Tina Fey and Amy Poehler plus Abbi Jacobson and Ilana Glazer of Broad City -- have joined forces to create a short, "Sisters Helping Sisters."

The clip, for Fey and Poehler's movie Sisters out this week, features the funny ladies dressed as nuns (get it, sisters?) trying to rein Abbi and Ilana in as they go on a crime spree including vandalism, gambling and harassing an old dude in the hospital.

Yaas! Hillary Clinton will appear on Broad City Season 3

"Here, take these and pray my child," Poehler says, handing rosary beads to Ilana, who assumes them to be um, another kind of beads. "I know what you're thinking of," Fey says. "This is New York City, we find them all the time in the confessional."

It's like the awesome fairy godmothers of comedy kicking it with their bad little sisters, and it's too funny. Check it out below.
