Not a biblical proverb, but an oft-repeated quote during the campaign months. It comes from Foster Freiss, a Rick Santorum backer. In a televised conversation with Andrea Mitchell (ugh) he commented thusly about contraception: “On this contraceptive thing, my Gosh it’s such [sic] inexpensive,” he added. “You know, back in my days, they used Bayer aspirin for contraception. The gals put it between their knees, and it wasn’t that costly."
It's one of the comments that was repeated over and over to make Pubbies look out of touch.
Ah, I see! I missed that brouhaha.
