The great Overdog
That heavenly beast
With a star in one eye
Gives a leap in the east.
He dances upright
All the way to the west
And never once drops
On his forefeet to rest.
I'm a poor underdog,
But to-night I will bark
With the great Overdog
That romps through the dark.
Frost wrote this poem in  dimeter , with each line containing two stresses from a combination of  iambs  and/or  anapests . Along with the rhymes every other line, this simulates a light romping or dancing feeling throughout the poem, mirroring the poem’s content. 
 
 The final line of the poem also contains an iamb (“That romps”) after four lines of all anapests. Thus, the stressed syllable, “romps,” is emphasized even more as the underdog joins in the dancing.
