I like that analogy.

Or, spam email - I have been told that spammers make a profit if just one in a (very very large number that I do not remember) email about Viagra gets opened and a purchase transaction gets made. But that is because the marginal cost of sending each additional spam email is virtually zero. What this woman advises: "Go out — alone. Look hot. Feel hot. Sit at the bar and get a drink." costs far from zero.
