When Ryan Reynolds appeared on Wednesday’s Late Night with Seth Meyers, the host didn’t just ask him about playing Deadpool. With a pregnant wife, Meyers also needed some baby advice from PEOPLE’S Sexiest Dad Alive. In true Deadpool fashion, Reynolds revealed that he had pulled a goofy prank on wife Blake Lively while she was in labor.

“I jammed a little Marvin Gaye, ‘Let’s Get It On,'” Reynolds said. “It was like steak knives came out of her eyes. ‘Are you —– right now?'”

On a slightly more serious note, Reynolds had some real dad advice for Meyers.

“Just do the dirty work, man,” Reynolds said. “You gotta do the diapers, you gotta do the middle of the night thing. A human being will exit your wife. She’s done enough.”
