Broad City stars Abbi Jacobson and Ilana Glazer stopped by the Late Show with David Letterman Thursday night to showcase their knack for "micro-impressions." That is, impressions that allow you to "get it in a second."

"No tomatoes, I'm allergic. Ketchup, pickles on the side," Glazer rapidly fired off first, impersonating Nicki Minaj ordering a burger at a Queens diner. "You don't need more than that."

Jacobson's impersonation was a little more subtle but equally as short. In silence, she stood up, walked to the edge of Letterman's stage, and dropped an imaginary jewel.

"Oh!," she said, impersonating Rose from Titanic.

"I really think you have something here," Letterman said in response. "Well, you're geniuses — comedy geniuses."
