A new favorite (country) song

John doesn't like country music to much these days. Sometimes he'll suffer through it...Just because he loves me.The other night he was being super nice and putting up with my VERY LOUD cleaning music. When this song came on he not only chuckled but I've heard him humming it a couple of times since. Shocking to those of us who live with him.After hearing the reason he liked it so much I thought I'd share it with all of his friends!See if you can guess why it meant so much to him. :)

PS. He wants to know what gun is best for this particular job...Any suggestions?
