In the Lonnie Mack songbook there is a slight diff :

2nd Verse is:

I keep in then cupboard, you know I keep em in jar
And for emergencies baby you know I keep em in the
glove compartment of my car...

And last verse:

Doctor says I'm crazy
Say's "Boy you better quit"
"Or you'll be pushing up daisies son cause you are definately sick"
