People think a wholesome 2009 Folgers coffee commercial featuring a young man and his teenage sister is actually incest porn and now I can’t unsee it.

Gabriella Paiella at GQ has an oral history of the commercial

Folgers Incest Ad: The Oral History of “Coming Home” for the Coffee Commercial’s 10th Anniversary:

“Coming Home” opens with a taxi dropping a young man off outside a snow-covered house bedecked in Christmas decorations early one morning. A young woman excitedly opens the door and establishes that she’s his sister by pointing at herself and saying “sister!” He’s weary, having just returned from volunteering in “West Africa,” and the two share a cup of freshly-brewed Folgers coffee while their parents are still asleep. (In some versions he even says “ah, real coffee,” as if he didn’t just come from where some of the best coffee in the world is produced.) He hands her a small present, but instead of opening it, she peels off the red bow and sticks it on his shirt. “What are you doing?” he asks. “You’re my present this year,” she responds. The camera zooms in on her shy glance, then cuts to his furtive, flirty smile. Those three seconds sealed its fate forever.

When I first saw the ad, I thought: wait, are they fucking? (Then, every time after that: okay, they’re definitely fucking.) As I would come to learn, I was hardly alone. The reaction to the ad was an example of the internet at its most fun—the phenomenon of collectively realizing that the specific thing that you believed you’ve singularly noticed is actually a widely-held opinion. Memes, articles, and parody videos abounded. It even inspired a genre of vividly-rendered fan fiction known as “Folgerscest.”

Mark Frauenfelder at Boing Boing: “Folgers should remake the commercial and hire the actors who played Cersei and Jaime Lannister.”
