I think maybe my all time favorite line is

"the beer I had for breakfast wasn't bad so I had one more dessert." from Sunday Morning Coming Down by Kristofferson


I also like this one maybe cause I'm from Alabama originally

"I'm in the heart of Dixie, Dixie's in the heart of me." from "My Home's In Alabama" by Alabama. Heart of Dixie is the state of Alabama's nickname or motto or something.


And there's a line in "I'm not ready yet" by George Jones that I like it because of the way he sings it: "Aw honey I know you ain't ever gonna love me."


And one more from another George Jones song "The Grand Tour:"
"As you leave you'll see the nursery, Lord, she left me without mercy."]
