In the film, however, Jennifer is actually married to Paul Rudd.
Jen and Paul are a couple who move from NYC down south and find themselves living in a commune.
Justin is one of the members who happens to play guitar and enjoy milking animals.
"Wrap your fingers around the base of it, work the shaft down to the tip and then… flick the tip," he teaches Jen in the trailer.
What a great story of how they first met!
