Looks can be deceiving

It's not your ordinary "rubber duck." Yes as a child you had one of those in the bath tub with you. But now they have one for women. I have this puzzled look as I was browsing through a website that sold it. How the heck does it work?

My friend finally explained to me that it's the beak that vibrates and pulsates. That way you can use it in certain areas, areas that need that special attention. I'm like "Oooooh." She started laughing. Then I said can you imagine your 4 year old son coming to you saying "look mommy, the duckie is shaking!"
