Stephen Colbert will officially kick off his reign as “Late Show” host on Tuesday, Sept. 8, CBS announced Monday.

Colbert, who ended his run on “The Colbert Report” in a wacky finale last month, was named David Letterman’s replacement last spring; the veteran late-night host had surprised everyone when he earlier announced his retirement. Letterman’s last night at the desk will be on Wednesday, May 20.

That’s a long time for Colbert to be off the air, which he acknowledged with a very Colbert-esque quote in CBS’s release: “I have nine months to make a show, just like a baby. So first, I should find out how you make a baby,” he said.
