Roadside Warning

A sign on the side of the highway Provoked my eyes to pop, ‘Cause what it said was “Prison near, So kindly do not stop.” Of course, we kept on driving But man, it made me think And wonder just how many men Have bolted from the clink. Envision those escapees, In their old-time stripy suits, Just lurking on the roadside With the warden in cahoots. For if inmates, as intended, Are locked up in cells with bars, Then why post a dire warning To the hordes of passing cars? It’s a puzzle so perplexing Who knows what it’s all about, But I’m sure all drivers question How the prisoners got out.
