US Patent and Trademark Office is one of the greatest repositories of practical knowledge in history. But along with a great deal of very serious and edifying material, much legally advised and/or required verbiage, and inventor-inspired general-purpose pleonasms, there are some items in their records that are highly amusing. In this series, occasional examples of such patents and patent applications are going to be extracted and put up for their amusement value.
After engaging in some particularly ill-advised and unreasonable activity, some people want to kick themselves after realizing what they have done; a device to help them do just that in a highly effective and amusing manner does exist.
