Our favorites were

Don't stick your elbow
Out too far
It might go home
In another car
Burma Shave

and

Twinkle twinkle
One eyed car
We all wonder
Where you are
Burma Shave


Real Burma Shave fans should look for the book "The Verse By the Side of the Road" which goes in and out of print every so often. I found my copy used. But it lists just about every Burma Shave verse ever used by the company.
