Just call Hamm the pregnant woman whisperer. Only he didn't exactly whisper ...
And by spoil, we mean he told the distraught star to get her "[something we can't print here] together" in order to put on their elaborate "Mad Men"-inspired sketch.
"I did the sketch, I was shooting with Hamm on Friday, and I called my doctor because at the end there you kind of have to call in every day, and the receptionist was crying. I said, 'What's wrong?' and she said, 'Oh, he passed away last night,'" Poehler recounted.
"I was due the next day. So it's my first kid, I'm in a 'Mad Men' outfit, I turn to everybody and I hysterically start crying, and a really pregnant woman crying is terrifying. So, juicy tears just like squirting out of my eyes. And it was like the punch line to a joke, it's like, my doctor just died and I'm due tomorrow.
"And Jon Hamm, who I am just getting to know, comes over and puts his hands on my shoulder and is like, 'This is a really important show for me. I'm gonna need you to get your [expletive] together.' And I laughed so hard, I probably peed myself," she said. "I believe that going through crying to laughing adds like five years to your life."
