Jeff, Who Lives at Home is a 2011 American comedy-drama film written and directed by Jay and Mark Duplass, starring Jason Segel and Ed Helms, and co-starring Judy Greer and Susan Sarandon.

One day, he answers the telephone; the wrong number is for somebody called "Kevin", and Jeff contemplates its meaning, deciding it is a sign.

Getting 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.

Seeing a truck reading "Kevin Kandy", Jeff runs off to hitch a ride, ending up at the same hotel where Pat has found Linda in a room with another man.

The doldrum is interrupted when a paper airplane with a drawing of a flower lands in her cubicle, followed by an anonymous co-worker claiming in an instant message to be a secret admirer.

He jumps out of the taxi and also runs through the cars, passing Pat, who was sharing his feelings with Linda when Sharon and Carol arrive.

Jeff sees a news report about his heroics, and learns that the father of the kids he rescued was also named Kevin; now with a sense of purpose, he grabs some wood glue and fixes the shutter.

The site's critical consensus reads, "Sweet, funny, and flawed, Jeff, Who Lives at Home finds the Duplass brothers moving into the mainstream with their signature quirky charm intact".

[7] Roger Ebert of the Chicago Sun-Times gave the film three stars out of four and described it as: a whimsical comedy [that depends] on the warmth of Segel and Sarandon, the discontent of Helms and Greer, and still more warmth that enters at midpoint with Carol (Rae Dawn Chong), Sarandon's co-worker at the office.... it's not a Feel Good Movie, more of a Feel Sorta Good Movie.
