Surprise-ercise!

   Sometimes when I lie around,
   Chilling out or snoring,
   Mom says I should exercise--
   Exercise? How boring.

   Or sometimes we might climb a tree,
   Or balance on a beam,
   Or dangle from the monkey bars,
   Or plunk rocks in the stream.

   Instead I trot around the block
   To see who's at the park,
   And if I find a pal or two,
   We'll race and play 'til dark.

   And finally when it's suppertime
   I find to my surprise,
   That what I thought was just good fun
   Was really exercise!
