Lover Spy, my new favorite piece of spam: an unsolicited offer to install spyware on a remote computer by sending that person an e-card, targetted at people looking to keep tabs on a lover:

Lover Spy is a spy program that monitors and records the complete computer activity of a computer user... The idea is to install this program on your lover's computer so you can check up on them. To do so, we have revolutionized the computer spy world by being the first company in the world to offer the following service:

Spy on Anyone by sending them an eGreeting Card.... Through our service, you compose and send your lover a normal-looking "Greeting Card" saying "I Love you" or a similar message. Because the e-mail appears to be a regular greeting card, the recipient will open the e-card and LoverSpy will be automatically and silently installed!

Who says innovation is dead...
