Can you beat this: <a href="http://www.mum.org">MUM.org: Museum of Menstruation</a> You'll be thrilled to see cool exhibits like the first <a href="http://www.mum.org/tampon36.htm">Tampax Tampon</a>, which were such a commercial success, because they were "Worn Internally" as noted on the packaging in the exhibit, as opposed to the tampon's predecessor <a href="http://www.mum.org/belts.htm">External Pad with Supporting Belt</a>.
If I had a dime for every time you mentioned menstruation, I'd probably have around 40 cents by now...
