I love that "If I had a hammer...."I was just about to say "What? Some person actually still likes that old song..?" ..when I saw the second part!
Can't seem to find just one line, but here's another bit of a song that grabs me:
Never hit seventeen/ When you play against the dealer/ For you know that the odds/ Won't ride with you/ Never leave your woman alone/ When your friends are out to steal her/ Years are gambled and lost/ Like summer wages/
