Those innovative Japanese are always cookin' up something! Never failing to be creative, the makers of reliable Toyota vehicles, snazzy Sony laptops [1] and crazy game shows now bring to you blow-up appendages.

So if you're a woman who has ever wondered what it's like to have a penis [2], you can just pick up a swan phallus. (Why swan? Must be some sort of Swan Lake reference considering there is a ballerina on the box.) And gentleman, you can grow some breasts!

These cheap little novelties work by way of some simple chemistry. Inside each gender-changing piece is a liquid packet, which when popped reacts with a powder that produces the gas responsible for inflating your stick-on swan.

Check out some photos and a video demonstration of both products here [3].

Definitely gives manboobs a new definition.
