The most popular when I was younger was the tale of the load of wet cement supposedly dumped in the cheater's sports car.
The details often differed but the main thread stayed the same - revenge!
Now an Australian woman has proven that 'truth' is stranger than fiction, if The Tech Herald is to be believed.
Specifically, the woman in question -- known only as "annastella007" through her eBay seller identification -- has held a public auction for a pair of lacy black panties worn by her husband's lover, and also an empty condom packet belonging to her husband....
eBay has since informed annastella007 that the sale of actual used underwear violates the service's sales policy, so the 'Tart's knickers' have now been replaced by a photo of the 'Tart's knickers'. The seller has reduced the price accordingly, stating that $0.99 AUD was perhaps a little ambitious.
The last time I looked at this eBay entry (which includes a story of the affair) the current bid had risen to US $31,849.62 with only 23 hours left to go in the auction.
I can hear a generation of deserted and divorced women cheering mightily and hoping that myth does indeed turn to fact.
