From Tina Fey’s Bossypants:
Amy was in the middle of some such nonsense with Seth Meyers across the table, and she did something vulgar as a joke. I can’t remember what it was exactly, except it was dirty and loud and ‘unladylike.’
Jimmy Fallon, who was arguably the star of the show at the time, turned to her and in a faux-squeamish voice said, ‘Stop that! It’s not cute! I don’t like it.’ Amy dropped what she was doing, went black in the eyes for a second, and wheeled around on him. ‘I don’t fucking care if you like it.’ Jimmy was visibly startled. Amy went right back to enjoying her ridiculous bit. I should make it clear that Jimmy and Amy are very good friends and there was never any real beef between them. (Insert penis joke here.)
With that exchange, a comic shift took place. Amy made it clear that she wasn’t there to be cute. She wasn’t there to play wives and girlfriends in the boys’ scenes. She was there to do what she wanted to do and she did not fucking care if you like it.
