Star Wars is expected to reign supreme this weekend, which puts the odds heavily against the Tina Fey and Amy Poehler comedy Sisters. In order to help promote the film, the funny duo brought in some reinforcements–Ilana Glazer and Abbi Jacobson from Comedy Central's Broad City.

In a short sketch,  Glazer and Jacobson play a couple of bad apples in serious need of an intervention. That’s when sisters (of the church variety) Fey and Poehler step in to teach them how to be moral. Things don’t go so well at first. The girls assume rosary beads are for a completely inapprproate purpose and their bong ends up getting confiscated.

Being bad is hard, okay? It’s not easy to leave a life of vandalism, gambling, stealing and hard partying behind. Eventually, they do come around and become the morally right sisters Poehler and Fey knew they could be. If you’re in the mood for sisters helping sisters, check out the amusing bit above.
