Nathan had been living with his mother long enough on "The Millers" that his sister, Debbie, and brother-in-law, Adam, started cracking jokes about the two of them dating. So Nathan helped his mother set up an online dating profile, where he learned things about her he probably didn't want to know -- like her attracting to masculine mustaches. Add to that Andy's obsession with "The Talk" throughout the episode, and the cameo by the women of the daytime talker at the end was perfectly set up.
The show came back from commercial with Nathan sitting among the ladies of "The Talk." But before wrapping up the show, they had one last surprise for him. "We know that you've been spending a lot of time with a very special lady," Aisha Tyler said, with Sara Gilbert picking up the thread, "And after 42 years, she wants you to make an honest woman out of her."
The curtains opened, and it was his mother in a wedding gown. And suddenly, Nathan was sporting a mustache. But all of this wasn't the strangest thing about the whole thing. It was a dream, of course, but it wasn't Nathan's dream -- it was Adam's.
Correction: An earlier version of this story incorrectly referred to Sara Gilbert as Melissa Gilbert.
