I'd seen references to Burma-Shave in Kingdom of Loathing, American Gods and now yesterday's xkcd, so I had to know what was up.
Burma-Shave was, surprise surprise, a shaving cream. But, what it's most famous for is it's marketing campaign, which ran from 1925 to 1963. The campaign was comprised of cutesy rhymes that were posted line-by-line on consecutive billboards, so you'd read them as you drove down the road.
I think what really shocked me was the number of examples they had in the article. Like, really. I'm not surprised that there are detailed articles on The Simpsons, but a marketing campaign that ended almost 50 years ago? I don't know if I'm impressed or weirded out.
Anywho, here were some of my faves:
1931: No matter / How you slice it / It's still your face / Be humane / Use / Burma-Shave
1936: Riot at / Drug store / Calling all cars / 100 customers / 99 jars / Burma-Shave
1947: I use it too / The bald man said / It keeps my face / Just like / My head / Burma-Shave
1952: The wolf / Is shaved / So neat and trim / Red Riding Hood / Is chasing him / Burma-Shave
Stick that in your pipe and smoke it, Geico cavemen.
