Don't you remember years ago when they were selling pet rocks?
They must have sold a truckload of those and people were dumb enough to buy them. Someone got rich, unfortunately it wasn't me.

Add to that list canned fresh mountain air, NYC tap water and a host of other schemes. Like they say, there's a sucker born every minute..... Gotta go now and put my bid in on the last hot dog sold at Yankee Stadium
