Do Not do What?

I know a manhole cover is not exactly exciting, but I have found myself noticing the smallest things now that I look at everything as a potential blip... (I wanted to blip an old man with a baby in the entryway of the Walmart the other day but I thought that he might think me weird)...I digress, I picked the manhole cover because I noticed that it says "Do Not Molest" on the right side - and it just sounded a little bizarre, like one of those google translations that doesn't come out quite right - well, it amused me anyway, so here it is - the gas meter manhole cover - I shall pass it a little more carefully in future ;0)
