Imagine season 7 finale: pregnant Cece preparing for Jess' wedding and going into labor seconds before Rob Reiner walks down the aisle with Jess. So Nick and Jess say their vows in Cece's hospital room after Cece has a baby and the doctor points at Cece's infant and says, "So who's that girl?" and Cece smiles at her friends and says, "It's Jess!" and credits roll.
