Rosie O'Donnell Channels Grease's Rizzo to Mock Donald Trump

There are many things out comedian and actor Rosie O'Donnell would never do. But mocking Donald Trump on Broadway, with a parody of an iconic song from Grease, is definitely not one of them. Especially when it's for a good cause.

O'Donnell took the stage in New York City during Thursday's curtain call for Disaster!, a raucous '70's-themed musical comedy currently on Broadway, to launch the latest salvo in her long-standing feud with the Republican presidential front-runner. BuzzFeed reports that cast members invited O'Donnell on stage after Thursday's show to help raise money for charity, while actor Seth Rudetsky recounted the pair's long history working together and writing parody songs.

As a fitting tribute, Rudetsky announced that he and O'Donnell had re-written the lyrics to Rizzo's signature ballad, "There Are Worse Things I Could Do," from the smash hit Grease, to relate to Trump's unfathomable political ascent.

Since at least 2011, Trump has targeted O'Donnell on television appearances and social media, hurling an untold number of insults at the out mother of five. He has belittled her appearance, her mental health, and at a presidential debate in August, reminded moderator Megyn Kelly that he had referred to O'Donnell (and other women he disliked) as "fat pigs, dogs, slobs, and disgusting animals."

Watch O'Donnell give it all she's got to reveal the things she'd never do below, in a video Disaster! posted on Facebook Friday.
