‘Smart’ by Shel SilversteinMy dad gave me one dollar bill
‘Cause I’m his smartest son,
And I swapped it for two shiny quarters
‘Cause two is more than one!
And then I took the quarters
And traded them to Lou
For three dimes — I guess he don’t know
That three is more than two!
Just then, along came old blind Bates
And just ’cause he can’t see
He gave me four nickels for my three dimes,
And four is more than three!
And I took the nickels to Hiram Coombs
Down at the seed-feed store,
And the fool gave me five pennies for them,
And five is more than four!
And then I went and showed my dad,
And he got red in the cheeks
And closed his eyes and shook his head–
Too proud of me to speak!
The choruses of the song introduce (and incessantly repeat) that 100 cents is the same as 1 dollar and (using the commutative property) that 1 dollar is equivalent to 100 cents.
