Dogbert stands on a conference table next to a laptop and an overhead projector. He says to the Boss, Alice and Wally, "I've reduced your service costs by giving the technical-support group an unlisted phone number." Dogbert continues, "And a flaw in your product disables the customer's e-mail; they can't even write to you for help!" The Boss asks, "What if they ask a friend to e-mail us?" Alice responds, "People who use our product don't have friends." Wally asks, "Really? I use it."
