But for Si Robertson, life wasn't always about long beards and duck call fortune.
Uncle Si reveals chilling details of alcoholism, mental illness and suicide in his new book, "Si-cology: Tales and Wisdom from Duck Dynasty's Favorite Uncle."
According to Radar Online, Si battled with alcohol abuse in his early adulthood, particularly while serving in Vietnam.
"Although I was there for only one year, it was a really difficult time in my life," he admits. But quickly, he found solace in alcohol.
The book also reveals a horrifying story of Si's son Scott, whose brain damage caused him to be suicidal at a young age.
"Scott was suicidal from the time he was about five years old. His behavior was really erratic as a child. When Scott would get tired, he would throw his arms out and fall backward."
Uncle Si's book is out now and available on Amazon.
