It’s surprising that some funny, disgusting viral videos can hurt a corporation’s image, while others can help (e.g., Keith’s SFW porn-viral for Diesel). The secret: good production values.  If only Domino’s had gotten Keith to direct that video (“pour an absurd amount of nasal fluid on that pizza, stat!”).   But also, the different receptions of these two videos stems from the different relationships between the product and the ‘disgusting’ act: unsanitary bodily fluids appear disgusting when associated with pizza, while jeans appear desirable when associated with sex (although some people would find the porn-sex disgusting, that reaction is offset by Keith’s funny SFW cartoons).
