Leave t to the UK to come up with some crazy a$$ sporting event like this. The Wife Carrying Championships have become quite the rage over seas. Basically it's an obstacle course where you as the husband carry you wife on you shoulders or back and try not to drop here.
This can be a really good way to bring a spark back the your relationship, or if you're a competitive couple this could be really bad if you lose.
And if you're wanting a laugh, check out what Ozzie Man has to say abut this as he reviews it. (NSFW)
