Kat Dennings "was in a rut." She needed something "to brighten her day."
So she tried jogging.
SBut Lipton was the only thing that made her feel better.
THE END FIN SCENE ETC.
I desperately wish I had been in the room during the probably months and months of discussion between Dennings' agent and the Lipton people over their excited discovery that Kat Dennings loves tea and Lipton's admission that they're trying to target a younger, hipper demographic and oh wouldn't she just be PERFECT for this new idea we have. And Kat just rolls her eyes and says, "Dude it's cool as long as the shoot is over in a day and the royalties come in on time, I'm good because I once had to fake an orgasm with Michael Cera. I can do anything."
