Elad:
Yes, I remember the Burma-Shave signs. I first saw them when the "Fancy" Burma-Shave was in a tube. That was "Brushless," you didn't have to put the soap cake in your shaving mug. Aerosol cans came many years later.
Another "Modernized" Burma-Shave sequence:
He took to wing,
. With a 91 OS.
The OS did its thing,
. Oh my, what a mess!
Kading&Brodbeck.
That's sort of a slam and plug combined. The OS 91 seems to be really unreliable, if you follow the threads in "Engines," and "Kading&Brodbeck" is, of course, K&B.
