Can you help me?

I shamelessly stole this from here

The newspaper had a contest for the wackiest web addresses. Here are some:

Who Represents?, a database for agencies to the rich and famous: www.whorepresents.com

Experts Exchange, a knowledge base where programmers can exchange advice and views: www.expertsexchange.com

Looking for a pen? Look no further than Pen Island: www.penisland.net

Need a therapist? www.therapistfinder.com

Mole Station Native Nursery, based in New South Wales: www.molestationnursery.com

New to Milan and you need electric light? Why not sign up on-line with Power-Gen? www.powergenitalia.com

I couldn’t figure out what is whacky about these web addresses. I may be color blind, may be you can help me?
