A walk on the pier ??

A couple was taking a leisurely walk along a pier. A speedboat came racing in out of control and hit the pier. When the pier collapsed, the couple fell into the ocean. Nothing was left of the pier but some upright pilings. As the man and women were treading water, the woman was holding her crying, "Oh, my titty-wittys, oh, my titty-wittys!" The man said, "Titty-wittys nothing. Look at my bally-wallys hanging up there on that rusty nail."
