New Girl First Look: Jessica Biel Plays the Mating Game on Season Premiere

Nothing says “Happy Hump Day” like a video about procreation from New Girl‘s season premiere.

In TVLine’s exclusive behind-the-scenes look at the comedy’s Sept. 16 return, Jess and Kat (guest star Jessica Biel) wage biological warfare — literally — over Ted, the best man at a wedding they’re both attending.

“Ted is the only eligible guy here, and we are his two best options for procreation,” Kat explains. “I am the better choice of mate, from a purely biological standpoint. You’re shorter, weaker and dumber — no offense, I love those shoes.”

From that point on, it’s a no-holds-barred battle for the best man, and not even Larry King — or at least a guy Jess thought was Larry King — is safe.

(BONUS: There’s also a nice blink-and-you’ll-miss-it moment between Jess and Nick around the 1:13 mark. A toilet is involved.)
