In this song called People are Crazy, sung by Billy Currington, it talks about him meeting an old man at a bar who teaches him a life lesson. The recurring line in the song is God is great, beer is good, and people are crazy. The whole song talks about how the old man who was a veteran and who was married and divorced. After they talked the old man died and left all of his fortune to the young man he had mat at the bar.
This song can relate to theology in many ways. You never know what you are going to learn from strangers. Just like on the road to Emmaus when Jesus interpreted the scripture when talking to the two disciples. Jesus would help anyone who asked for it. He would help others just like in the song. When one listens to the advice from the knowledgeable, it can change their life.
