spammers

some representative email subjects from today:
fw: seersucker cunning
fw: starfish synthesis
fw: ...
fw: carl cinnamon

Now admittedly, I'm an IT geek, so I know not to open these, but who in their right mind would respond to "seersucker cunning"? What could it be? How to wear seersucker surreptitiously? How to look especially smart whilst wearing seersucker? (Give up!) And supposedly, these things grab words from other emails in your box. Seersucker??? When have I last emailed about seersucker? OK, so NO. That's not it. And frankly, the seersucker and starfish subject lines make more sense than most of the ones I get, as far as normal words and grammar is concerned. (carl cinnamon????)
What I don't get is if these spammers want us to open their infected mail, why don't they just use real language and subjects that make sense? Until they wise up, I guess it's nice to have that heads up.

Sandtoy motoring anyone?!
