Pfizer PCs used to relay Viagra spam

Viagra is a Pfizer product, so perhaps they're not too upset about these trojans.  Naah.  PCs at Pfizer have been hijacked by trojans, which are using them to forward Viagra spam.
At least 138 of Pfizer's IP addresses are being used to send the spam after being loaded with Trojan software, it emerged this week. Aside from Viagra, the spam advertises penis-enlargement drugs, fake Rolexes and shares, according to botnet-tracking company Support Intelligence, which said that those IP addresses have now been blacklisted by anti-spam companies.
Embarassing?  Ironic?  Funny?  Or all of the above?
