...Mopars are always way out back
Between the muddy river and the rusty railroad track
Yeah, the Mopars are always hard to find
But you can always find a few
There’s Cordobas and Furys and Darts and Dusters too
There’s a Diplomat with a Swinger
A new Yorker a Demon and a Scamp
And there’s a 68 Barracuda grill with both headlamps...Slaid Cleaves - Skunk Juice
