'Duck Dynasty' Season 4 Premiere: Cast Unites for Phil and Kay's Wedding Anniversary / Air Date: August 14 at 10/9c on A&E

The beards are back!

Duck Dynasty returns for its Season 4 premiere Wednesday night. By the looks of it the Robertsons are back to their old antics. Part of the plot line for the Season 4 premiere has already been revealed online.

Bearded patriarch Phil Robertson and his wife Miss Kay are celebrating their 40^th anniversary with a party and ceremony for the couple to renew their vowels.

A sneak peak into Season 4 shows Phil's sons and friends in wedding mode donning ill-fitting tuxedos. The sons are visibly out of their comfort zone in the scene.

When the Robertson ladies show up, Willie's wife Korie points out a big mistake in her husband's fit.

"Willie, your crotch is like at your knees," Korie Robertson tells Willie. Oh the innuendo.

Willie responds: "Its maddening buying pants."

Season 3 o the popular A&E series broke records for the network drawing around 10 million viewers each episode.

The Robertsons currently have two NY Times Bestselling books. One is a memoir from Phil ["Happy, Happy, Happy"]. The brand isn't dying anytime soon. Three more books are expected out this fall.

Also on the horizon? A Christmas album, a cruise and a line of prom dresses.

Tune in for the Duck Dynasty Season 4 premiere, Wednesday August 14^th at 10/9c on A&E.
