Friendster
Circumstances involving bookmyband required I join Friendster today. So I've got only one friend in the network and yet I find this:
Your Personal Network currently contains 67182 people.

You can increase the size of your Personal Network by Inviting more friends.

Egads! Why would I want to increase the size of my Personal Network if it's already the size of a small city?

--P.S. If you want to endure the server lag and find me on Friendster, it's ann@bookmyband.com. Because I really needed that twelfth email address...
