What is the name of Jeff's sister in law?  Answer the above question based on the context below:  Jeff is a 30-year-old unemployed stoner living in his mother Sharon's (Sarandon) basement in Baton Rouge, Louisiana. He looks for his destiny in seemingly random occurrences. He finds inspiration in the feature film Signs, which reinforces his belief in this outlook. One day, he answers the telephone; it's a wrong number, from somebody asking for "Kevin," and Jeff contemplates the meaning of this, deciding it's a sign. Receiving a call from his irritated mother asking him to buy wood glue to fix a door shutter or find a new place to live, Jeff boards a bus, where he sees a kid wearing a sports jersey bearing the name Kevin.  He follows Kevin to a basketball court, where he joins a pick-up game and the two bond.  Jeff agrees to smoke weed with Kevin, but discovers he has been tricked when he is beaten and mugged. He happens upon a Hooters restaurant where he crosses paths with his older brother Pat, a successful yuppie struggling with a failing marriage. Pat's wife Linda is spotted at a gas station across the street with another man. Jeff and Pat spend several hours following them, first to a restaurant and later to a hotel, with Pat's new Porsche being ticketed, crashed and eventually towed away at various points in the journey. The brothers also visit their father's gravesite and fight over their conflicting life philosophies.
