Is this a wind-up

In the winter of 2005 whilst snowboarding we convinced Allen that there were snow crabs in the swiss mountains. Most would find this amusing, some lacking a sense of humour, cruel. We were not so cruel that we didn't come clean by the end of the day.

Recently though I was told of a Swiss tradition, which to me sounds like a wind-up. If not, it's a rather disturbing tradition. If true I'm sure Swingen (swiss wrestling) champions are not too often invited to friends weddings:

...in cantons such as Argau and Solothurn, there is a tradition that immediately after the church service, every bachelor in the congregation is expected to wrestle with the groom in order that he might prove his suitability as a husband. Large, baggy shorts are provided for this purpose, and most churches have a sandpit in the rear for exactly this purpose.

Should one of the bachelors beat the new groom in the wrestling match, then he is invited to spend the first night with the hapless bride, with the groom being forced to spend the night outside the window.

Over recent years, this has become a simple ritual, with the bachelors in the congregation putting no real effort into the fight, for fear of sullying the groom's honour.

No one will tell me if this is true or not though. It would add a rather interesting twist if the Swiss were ever to re-make the film 'The Wedding Crashers'.
