3291 - Pun

"You don't have to put on the red light."

I could have looked at this forever and not gotten the pun. Are you a music aficionado? Specifically a fan of The Police. Well the pun is about the song Roxanne. The truck has it's red light on. The line from the song is ... 'Roxanne, you don't have to put on the red light.' Rock Sand ... Roxanne...

If I hadn't looked at the comments in the post I would have never have understood.
