Here’s a clip from Broad City stars Abbi Jacobson and Ilana Glazer’s visit to last night’s Late Show, where they explain to Colbert why it’s no longer cool to explain what’s cool before introducing him to the newest New York food fad: rainbow bagels. This leads to a magical trip to “Happy Bagel Place,†which, it turns out, isn’t as happy as it looks on the surface, but hopefully all three come back from the trip alive.
