Meanwhile, Ellie worries about Stan's behavior after a series of destructive streaks.

To avoid hurting anyone's feelings, Jules asks Laurie and Ellie to be her co-maids of honor. Chick (Ken Jenkins) decides to have a little fun when Grayson asks him for Jules' hand in marriage. To show he's okay with their marriage, Bobby installs a zip-line from Grayson's house to Jules'.
