Bayer Back & Body If you think you’ve been hearing the phrase bareback—slang for condomless anal sex—during TV commercial breaks, you’re not going crazy. It’s an ad for Bayer Back & Body pain relief. But said out loud, it sounds like “bareback and body,” as in: “Bareback and body’s dual action formula includes aspirin, which blocks pain at the sight. Try the power of bareback and body.”

Also in the “what were they thinking” Mad Men category: those recurring ads for “Active Tops” and “Active Bottoms” clothing items. Belk department stores recently took this to a new (low) level with posters picturing an African-American male model and reading: “The Spring 2013 Most Wanted Colored Bottom.”

And let’s not forget the popular diet candies of the 1970s and early ’80s named, you guessed it, Ayds (pronounced AIDS). Not surprisingly, once HIV/AIDS hit, sales plummeted and the product was shelved.

Remember, folks, after antiretrovirals, laughter’s the best medicine.
