A brushless shaving cream which is best known for its clever advertising. The rhyming jingles were placed on consecutive signs along the highway so they looked like this:

THE BEARDED LADY
TRIED A JAR
SHE'S NOW
A FAMOUS MOVIE STAR
BURMA-SHAVE

The signs were popular from the 1920s through the 1960s, when they were retired to make sure that all American advertising sucked.
