Bouncing Brianna

Each morning Brianna goes bouncing to class.
She bounds on the playground and springs in the grass.
Her gallop1 is more of a jump than a jog.
She leaps like a rabbit. She hops2 like a frog.
Her teachers dislike it, except at P.E.
when Bouncing Brianna can spring like a flea3.
She's always the best at gymnastics, it's true;
the pole vault4, the high jump, and trampoline too.
It's crazy to watch her on basketball courts,
and yet there's a reason she's awesome5 at sports.
We know why she hurdles6 and bounces off walls:
For breakfast she always eats hard rubber balls.
