Garth Brooks graduated from Yukon High School in Yukon, Okla. in 1980 and went on to earn an advertising degree from Oklahoma State University in 1985. It was a surprise to everyone in attendance when in May 2011 Brooks' name was called to the stage to accept his Master's degree during the university's commencement ceremony. This wasn't an honorary degree -- Brooks went back to school. This photo shows him smiling with fellow grads on that day. Those in attendance admit the singer received the biggest applause.
