Urban legend

This example of yet another revenge-based adultery legend spread throughout the USA and Canada in mid-1985. Although the bride was usually the wronged partner, Brunvand reported that gender-switched versions in which the groom walked out on the wedding were circulating concurrently with the original. In late 1995 a more elaborate version with a male protagonist swept through the media and circulated widely on the Internet. This updated version (shown in the second example above) is more than a mere gender-switched version, however — it adds an extra helping of virtriol to the tale. Where the bride had been satisfied with voicing her grievance, throwing flowers in the groom's face, and walking out of the church, the groom is determined to make his bride suffer as much pain (both emotionally and financially) as possible.
Note the much coarser feel of the second version. The groom is not content merely to announce his bride's unfaithfulness: he provides every single guest with photographic proof, stays around long enough to savor their reactions, and spouts obscenities at the bride and best man. Moreover, his main motivation for the whole scheme is revealed as the desire to stick the bride's parents with the bill for a large wedding, even though it means actually going through with the legal process of getting married. (This last point makes little logical sense, as the groom could have walked out at any time during the ceremony and still have accomplished the same goal.) This version is almost as much about the what a great prank a "guy with balls" can pull off in "his world" as it is about the fragility of romance and friendship. The legend may have picked up this extra "emphasis" in its latest go-round because monogamy and faithfulness are especially important in the era of AIDS, where a lack of commitment can ruin much more than a marriage.
