I came across this awhile ago on snopes, but I forgot how funny it was until I stumbled upon it again.  Basically, it’s about domain names registered by companies who may not have realized what they were registering:

Italian branch of PowerGen          powergenitalia.com 
who represents?                    whorepresents.com
Experts Exchange                        expertsexchange.com
Mole Station Native Nursery     molestationnursery.com
and of course
Pen Island                              penisland.net
