Well the picture in the paper showed the scene real well
Papa's rig was buried in the local motel
Yep, he drives his semi into the motel room where she's holed up with her one night stand. You have to admit, "Papa" was creative. Significant others in other tunes have been stabbed, shot (a popular option) cut with a razor, and beaten with sticks. They've also been tied to chairs, then shot. I'm pretty sure that "Papa Loved Mama" was the first song that involved death by truck.
