Late-night TV is preparing for a milestone Tuesday night: It’ll be the first State of the Union address that a Trump-obsessed genre gets to sink its teeth into. The hosts took some batting practice on Monday night, and landed quite a few zingers.

“Tomorrow night, of course, is President Trump’s first State of the Union address. He’s not scheduled to appear in front of Congress again until the impeachment hearings.” — STEPHEN COLBERT “The State of the Union is the one day of the year presidents are supposed to brag about their accomplishments. So he’s been training for this, really, for his whole life.” — JIMMY KIMMEL “They released the theme today. It’s ‘Safe, strong, proud,’ based on the three words he never heard from his father.” — JIMMY KIMMEL

“You can tell he’s serious about it because today he hopped on his computer and googled ‘how to do State of the Union address.’” — JIMMY FALLON

“White House press secretary Sarah Huckabee Sanders said today that President Trump’s State of the Union address tomorrow is must-watch TV. Incidentally, ‘must watch TV’ is also the first thought that goes through Trump’s head when he wakes up in the morning.” — SETH MEYERS

‘Uniom’

The House sergeant-at-arms distributed a batch of erroneous invitations to the State of the Union, misspelling it “Uniom.” Mr. Kimmel and Mr. Colbert had some nonsensical fun with it.

“If I’m not mistaken, the Uniom was the side that won the Civil Warm. Isn’t that right?” — JIMMY KIMMEL “Maybe, just maybe, it’s not a typo. I mean, Donald Trump said he would shake things up, he would change things. Maybe tomorrow will be the first State of the Uniom. ‘My fellob Amerimicans: with Dolin Trunk as your predisent, every mang, woban and chilm will know: The state of our uniom is strog. So strog.’” — STEPHEN COLBERT

The Punchiest Punchlines (Logic Edition)

“A lot of artists called out Trump’s immigration policy, including Camila Cabello, U2 and the rapper Logic. Not the first time Trump and logic have been at odds.” — STEPHEN COLBERT, on the Grammys “President Trump will deliver his first State of the Union address tomorrow, so if you want to know how the country is doing: The State of the Union is being delivered by Donald Trump.” — SETH MEYERS

The Bits Worth Watching

Mr. Kimmel wants to see a rap battle between Jay-Z and Mr. Trump: “Winner gets to be president.”
