I need the name of a song. I can only remmber a small amount of it. It has a man and a woman trading lines. It is supposed to sound very bluegrassy and folksy, but it is a modern song, I believe. One of the lines that I remember has the man saying "ain't got laid in a month of Sundays" I cannot remember the rest. If anyone can help, you will be much appreciated!! I'm sorry if this request os too vague, but I have been trying to figure this out for about two years!!!

Thank you!
