Is Robert Ludlum trying to sell me Viagra?

I have been getting an increasing amount of spam lately that my filter is not, well, filtering. It's almost all prescription drug ie. viagra, levitra etc. I'm not sure if the word on the street is that my junk is inoperative but let me quell all those rumors by...well you'll just have to trust me. The strange part about this spam is that it all contains short text from Robert Ludlum novels, mostly The Bourne Supremacy. I find it doubtful that R.Lud is pimping the little blue miracles but why is someone bothering to add this useless text to an already useless email? Strange....
