Knowing Mary Jane's Pet Skunk

Recently I was putting our six year old into the car, when he said something. I didn't know what was happening at the time, and I had my back to the action. But he said, "Hey, what's that icky smell? It smells like skunk. (pause) Oh, it's a cigarette." I smelled it after he said it smelled like a skunk. I could tell that there were some people on the other side of the car next to us, but they walked away before I could turn around. Yep, skunk weed it was. My six year old knows Mary Jane.
