Fifteen sexist vintage ads. mmMMMmm, Lysol douche. No, seriously, they did.
See, that proves it, though: it's -good- to use "douchebag" as an insult, because what you're actually saying is
"Dave? I need you like I need Lysol in my cooch. Byieeeeeeee!"
h/t various folks on Twitter including Neil Gaiman.
ETA: if you're interested in this kind of thing, Pink Think has more. and yes, I believe the book includes the Lysol douche ad, albeit not that particular iteration, with the locks.
