"Little Deuce Coupe"

While reading The Beach Boys yester-day, I ran across the phrase "Deuce Coupe" (on page 287, Dennis mentions a ballet with this name, inspired by the Beach Boys' music).  In thinking about the song "Little Deuce Coupe" afterwards, I realized that the second half of the line "Well, I'm not braggin', babe, so don't put me down" is sung to a descending melody ("so don't put me down" is sung to the notes Db C Ab Ab Ab), so while the expression is used more metaphorically and is negated, there's a musical sense of "put[ting]... down."
