When Stephen Colbert signs off permanently tonight, it'll also mark the end of an era for several "Late Show" staffers who got their start in Chicago.

The latest: "The Late Show With Stephen Colbert" is ending its run after CBS canceled the show, having produced nearly 1,800 episodes.

State of play: Colbert, who came up through The Second City, has hired many writers from Chicago over the years, including for his "Late Show" staff of more than 20 writers.

Between the lines: With Colbert off the air, Second City loses one of its biggest pipelines for placing up-and-coming talent in late-night.

What they're saying: "There's a kind of creative shorthand for comedy makers that have gone through the Second City ecosystem," the theater's Kelly Leonard tells Axios.

By the numbers: Writers with Chicago ties — some dating back to "The Colbert Report" days at Comedy Central — have included Paul Dinello, Tom Purcell, Ariel Dumas, Brian Stack, Jen Spyra, John Thibodeaux, Asher Perlman, Steve Waltien, Carley Mosely and many more.

The bottom line: Wherever Colbert lands next, don't be surprised if Chicago writers follow.

When to watch: "The Late Show with Stephen Colbert" airs its final episode tonight at 10:35pm.

Memorial Day weekend marks the launch (or at least soft launch in chilly Chicago) of the summer season.

• Here are some ways to spend the long weekend.

🌺 Fleurs de Villes

• This exhibit is about more than flowers. It's fashion, creativity and mastery of the craft. Plus, cocktail and tea parties!
• Thursday-Monday at 900 North Michigan Shops, with a couple of installations at The Ritz-Carlton and the Four Seasons.

💭 Carrie's thought bubble: I was a judge for the show and was blown away by what these artists can do with fresh flowers and plants. There were dresses I would love to wear ... I'd just make sure my husband watered me throughout the night.

🦖 Dinos! at Brookfield Zoo

• Jurassic Park in the burbs! Visitors (young and old, let's be honest, dinosaurs aren't just for kids) can walk through a dinosaur ribcage tunnel, dig for fossils and get up close with a T. Rex.
