When Ken accidentally finds out that Clark and Connor are planning their surprise wedding, he has to find a way to get everyone to come. But Damona finds out and to get Allison there, she tells her that Ken is going to surprise her by renewing their wedding vows. Guest performances from the Grammy Award-winning band, Train, featuring lead singer Pat Monahan and guitarist Jerry Becker.

After an awkward audition with Alison Brie, Hollywood producer/writer Dan Harmon makes Ken's life-long dream come true by casting him in a new comedy series that takes place at a community college. Meanwhile, Pat is ready to declare his love for Damona, but an unexpected visit from his ex-wife, Tiffany, throws him off course; and Allison is less prepared for Molly to leave for Stanford than she's letting on.
