iPhone's auto-complete automatically changed "STOP" to that.
Phew, and to think I was just about to walk into that pitch black collapsed rock hole.
If it were me, I would walk in the dorm room with this and say "Are you guys ready to ROCK?!?"
"We just had to stop and take a picture of this sign at our local liquor store."
"My buddy stole this, changed the sign and put it in the front window of his house."
One sexy stop sign...
