Duck Dynasty >> Season 4

The church can't host their annual trick or treat event so the Robertsons offer to hold the event at Duck Commander. They all come together to decorate the warehouse and transform it into a "scarehouse." Everyone dresses up and Willie desperately tries to be the scariest, but none of the kids are afraid of him. Meanwhile, Kay is decorating her house for Halloween and enlists the youngest kids to help her. When they try to get Phil into the Halloween spirit, Phil puts his own twist on Halloween decorating by making a jack-o-lantern with a shotgun.

Si discovers Youtube, and, after watching a series of instructional videos, decides he can make something better. Jase, Jep, Godwin, and Martin help Si shoot an instructional golf video, and upload Si's "four point philosophy" to the web. John Luke totals Willie's truck, and Willie realizes he may be raising the two worst drivers in all of Louisiana. Willie then remembers that all kids are trouble when he takes his niece and nephew for a ride in his loaner, a 2014 Chevy Silverado, and they cover it in ice cream.

A decision to try and make some duck jerky leads the boys to Godwin's garage, where they end up fighting hornets and racing motorcycles before finally creating the jerky back at Duck Command after an impromptu knife throwing competition. Phil and Kay have made Willie the executor of their will, and Phil wants to show Willie what he and his brothers will inherit when he and Kay pass away.

Si shows up to work on a mobility scooter, claiming to have an invisible injury from a fender bender with Willie. After losing her beloved turtle "Mr. T", Ms.Kay enlists Phil on a mission to find a new pet turtle.

John Luke and Sadie are getting some dental work done, complete with sedation, and it's up to Willie and Korie to take care of them through the process--including getting them back home safely. Phil goes to DC to recruit Jase and Jep to help him take care of a cottonmouth den and finds them emptying the contents of the broken fridge into trash bags. They set out to dump the trash but keep running into problems.

Because of a termite problem at Duck Commander, the guys are forced to find a different location to work from--Godwin's House. But while at Godwin's house, Godwin gets a taxidermied gift from a past relative, which sends them on a mission to find out how much it is worth. Miss Kay needs help with her Golden 60's club, so she enlists Korie and Willie to help her out.

The guys realize that Godwin has never really asked them for a favor, even though they are all always helping each other out. Godwin asks them to help him get a hot tub, so they set out to help him pick one up. Phil and Kay teach Sadie and John Luke how to make May Haw jelly.

After discovering that Martin has to miss a Friday night poker game for a planned date, the guys (as well as their wives) take turns figuring out the best way to coach him for romance. When babysitting for Jep and Jessica turns into a rocky road, Phil tries to teach his granddaughters how to fish--a useful skill. But even at this young age, the girls outsmart him and have him doing all the work.

Everyone comes together to plan a surprise wedding for Phil and Kay, setting up a special ceremony on their land, which the whole family attends. Si distracts Phil and Kay by taking them on a "trip down memory lane" to different places that were meaningful in their relationship.
