penisland was another famous site from the time with this property.

Edit: It was a site that sold pens; I think the alternative pronunciation of their domain name was unintentional.

Edit 2: I think I was wrong. Snopes says they did sell pens but they chose the name intentionally: http://www.snopes.com/business/names/domains.asp. Some other such names from that link: powergenitalia.com, molestationnursery.com, and whorepresents.com.
