Are they talking about trees?

A couple of days ago, I was driving down Detroit's now-infamous 8 Mile road. It really isn't anything all that spectacular. However, there do happen to be a lot of strip clubs on 8 Mile. So, I was sitting at a traffic light and looked over to the side. There was a telephone pole with a sign tacked to it. The sign said "STUMP GRINDING" and listed a phone number. In the background was the strip club the Booby Trap. I laughed my ass off. I'm assuming the sign was advertising a service that removes tree stumps, but with the Booby Trap right there, it just seemed like the ad was for something else. Sometimes I have a one-track mind.
