"Duck Dynasty" Season 4 is underway on A&E and the ratings have been staying strong following the Robertson family around. 

Si Robertson recently sat down with Lifeway.com to share about the success of "Duck Dynasty" and God's sense of humor. 

In typical Si Robertson fashion, he shares some good one lines like, "A lot of people say 'Hey, God does not have a sense of humor'. Yes He does. God has got a great sense of humor. OK. Because, hey, look at me and look at Phil and look at Willie and look at Jason. God has taken four guys that look like about five miles of muddy road and made them famous in the TV world." 

Si then shares that the key to all of this success is 'God, the One Almighty'.
