Rosie ODonnell ends Kimmel run with a ballad for Trump

Rosie O'Donnell concluded her Jimmy Kimmel Live! guest-hosting week with a musical middle finger to Donald Trump .

A longtime critic of the president, the comedian and screen legend has been starting every nightly monologue with a thinly veiled dig at Trump.

On Monday, O'Donnell called the president "Mango Mussolini." On Tuesday, "President Oompa J.

Loompa." On Wednesday, "President Petty Roosevelt." And on Thursday, the host paid tribute to the "Hungry, Hungry Hypocrite in the White House" with a ditty.

To close the monologue, O'Donnell sang a parody of the traditional folk song "Danny Boy," a song often associated with her new home of Ireland, and it's pure cinema.

"Poor Donny Boy, your polls, your polls are falling / Your reflecting pool is green as Mountain Dew / Your wig's a mess, your ballroom is appalling / And with Iran, you bit off more than you can chew," O'Donnell sings.

"But there's a way to end this job / It's time to use that stable genius brain / Since we all know you'll never be Obama / Why not resign and make this country great again?"
