How creepy is this? I think she’s actually rubbing listerine into that kid’s head and he says it feels “swell.” Now I know things were different in 1934, but when I was a kid you rinsed your mouth out with listerine. You didn’t pour it on some kid’s head. (OK, my grandpa rinsed his mouth out with listerine, I didn’t.) So what else were they doing with listerine back then? Do I even want to know? Swell.
