Rosie O’Donnell drilled nemesis President Donald Trump for the last time as guest host of “Jimmy Kimmel Live” on Thursday. And she made it count.The comedian and former daytime talk queen, who moved to Ireland amid her feud with the president, zinged him in word and song. She brought down the house with a “Danny Boy” parody for “Donny Boy.”In earlier remarks, she thanked “everyone who’s been watching this week, especially the hungry, hungry hypocrite in the White House.”She also noted that “it’s kind of weird to think he spent more nights with me this week than Melania.”She got serious, too: “Most of all, I’d like to thank Jimmy Kimmel for inviting me to do this and for reminding everyone that we have the right to free speech in this country, whether Orange Voldemort likes it or not.”But the showstopper was her song. “Poor Donny boy, your polls, your polls are falling,” she sang. “Your reflecting pool is green as Mountain Dew. Your wig’s a mess, your ballroom is appalling, and with Iran you’ve bit off more than you can chew. Measles are back, inflation is a-swelling; you post all night, you’re sleeping while you work. And what’s with all this useless crap you’re selling? Hey, sweetie pie, you’re driving us all berserk. But there’s a way to end this drama. 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?”
