All the jump rope songs with counting that I know are in the present tense, so I'd suggest "does" or "will" rather than "did" ... except the Lizzie Borden one. And the shipshun one, come to think. Maybe I'm just wrong about this.

But "axe" and "attack" almost rhyme in a way that makes me think it would in oral tradition, and goodness knows jumprope rhymes are oral tradition, become "attacks" however ungrammatical that is. How's "Count the girls that Twist attacks!" ? Or "Count out"? Or "See the pretty girls that Twist attacks! One, two, three..."
