Duck Dynasty’s Uncle Si Robertson is celebrating his 65th birthday today, April 27.
Silas Merritt “Si” Robertsonis Phil’s youngest brother, a Vietnam War veteran, and married to Christine (who isn’t featured on the show).
Si Robertson works at Duck Commander, making the reeds that go into every duck call.
America’s favorite uncle is kind of like the Kramer of Duck Dynasty.
He is known for his storytelling, his constant use of the phrase “Hey!” and his ever-present blue plastic cup, which his mother sent him while he was stationed in Vietnam.
Uncle Si is often filmed carrying around a jug of sweet tea and he loves pizza.
