The clock strikes 6 a.m. and Phil gets up to run to the Groundhog Festival. He immediately runs into Nancy from the diner and uses the info he knows about her to start a conversation. He pretends that they went to high school together.
The next time we see them, Phil and Nancy are making out on a couch in front of a fire.
Phil accidentally calls Nancy Rita. But he gets out of it by saying that he loves Nancy and wants to marry her.
Rather than being weirded out, Nancy finds this romantic. Phil accidentally calls her Rita again, but they keep going anyway.
