John assumes that Joan's creative writing teacher has a crush on her; Tyler and Clementine have Matt and Colleen over for dinner; Lark takes her first steps while Greg is away on business; and Colleen, Heather, Jen and Dougie have a ladies night out.

When John decides to try out for "Survivor," Tim gets jealous and attempts to undermine his audition tape. Also, Colleen confesses she can't swim when she and Matt discuss Hawaii as a honeymoon destination; Jen pretends to get hooked on meditation so she can use the time to play cell phone games; and Heather gives Sophia the "sex" talk.
