Musical guest stars are plentiful in "Facebook Fish Planner Backstage," with Charlie Puth playing himself — and generously giving Tim (Dan Bakkedahl) tickets to attend the Grammy Awards. Lyle Lovett also appears as Matt and Colleen’s (Thomas Sadoski, Angelique Cabral) wedding planner, whose unusual manner gives them concerns about their upcoming event. John and Joan (James Brolin, Dianne Wiest) join Facebook. Colin Hanks also stars.
