A primitive version of Last Measure was concieved by Penisbird of the GNAA after playing with an AIM utility named AIM Invader. It offered Penisbird a myriad of ways to crash AIM clients. By far the most powerful crash was the "last measure" crash, which would inundate an AIM client with file transfer requests, buddy list sends, messages full of smileys and colors, until the AIM client crashed due to lack of RAM.
the Last Measure site originally consisted of Penisbird, Goatse, Tubgirl, Lemonparty, and Shitfaced Lady.
