Some celebrities aren't just pretty faces. A few of them are also touched with that Yankee prowess for tinkering and invention. In this weekly series, we introduce you to the Patents of the Rich and Famous. And maybe you learn a little bit about how patent literature works along the way.

Inventor: Penn Jillette

Known For: He is Penn of Penn & Teller, that quirky magic duo that performs in Las Vegas and sometimes makes cameos on shows like Top Chef. He's the talky one. They also have a Showtime program called Penn & Teller: Bullshit! where they debunk pseudoscientific ideas and conspiracy theories--it's like a PG-13 version of MythBusters.

Penn is also very sexy. Have you seen that mane?

Or, at least he gets Liz Lemon going, as she noted in last night's 30 Rock, when lamenting her inactive sex life with current boyfriend Carol (played by Matt Damon):





Not even after Penn & Teller? Bummer.

Given Jillette's effect on women, it seems logical that he would patent an invention just for the ladies. Thanks, Jillette.

Invented Apparatus: "Hydro-therapeutic stimulator"

At first glance, it looks like a bathtub. But then, you think, why is there a naked lady in that tub? And, what is that smirk on her face? Well, that's because this isn't just any old spa, it has a special function:

It is therefore an object of the present invention to provide a spa that includes a dedicated stream of fluid that is directed to specific sensitive areas of a female's genitalia to promote pleasurable (and perhaps climatic) genitalia stimulation and therapeutic relaxation.

It's a lady pleasure tub! While many baths incorporate water streams, Jillette's patent has a jet where it counts:



The spa has a seat for supporting the female user in a seated position, a circulation pump having an inlet connected to the tub for drawing water from the tub, and an outlet connected to the tub for discharging the drawn water back to the tub. A discharge nozzle is located within the tub and connected to the outlet, mounted to the seat so that the discharged water from the circulation pump automatically aligns with and is directed to stimulation points (e.g., the clitoris) of the female user when the female user sits in the seat.

He calls it the Jill-Jet. For Jill, by Jill(ette).
