On a whim, I typed “unusual thing” into Google and got this page on a site called Russia Makes It FunnyLink

Women’s panties with alarm appear soon

An unusual thing was invented by Serbian Slavomir Adamovic. Ladies panties with an alarm will appear soon. As it is well-known, sexual abuse against women is rather frequent in offices. The invention will emit loud peeps every time its owner is pinched at her butt.

The inventor hopes, such unexpected sounds will cool sexually concerned men in the office and will make office a safer place, free from sexual terror. Slavomir Adamovic says, the panties peep because of a micro chip embedded into underwear and emits sounds when being pressed, or when areas close to the underwear are pressed.

What can I say? Slavomir, you’re a genius.
