I meant to post this earlier but forgot. I never manage to notice who the sponsor is until I watch the episode a 2nd time. (I think my brain is always too busy going "Eeee!" or "Hmmm..." during the first viewing to actually notice commercials.)
Last week's "official" sponsor (of The Rapes of Graff ) was Duracell batteries. Link to contact is here:
http://www.duracell.com/company/contact.asp?id=58& (you can call or write. there's a way to email, you have to hit the "Gillette Contact" button - Gillette is the parent company)
This week's sponsor... I don't know. I watched it and then accidentally taped over the episode so now I can't rewatch it. :( Anybody else catch this week's sponsor? (It's announced at the first commercial break.)
