In July 1999, Jillette was granted
U.S. Patent 5,920,923 for the "Jill-Jet", a hot-tub jet specially angled for a woman's pleasure. He has credited
Debbie Harry of
Blondie for suggesting the idea, as the two of them were once in a hot-tub and Harry made a remark about changing the jets for a woman's pleasure. Jillette liked the idea enough to pursue patent application at the
USPTO under the patent title "Hydro-therapeutic stimulator".
[18] The abstract of the patent explains that 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 of the female user when the female user sits in the seat."
