Question

Three brothers share a family sport: a non-stop marathon.

The oldest one is fat and short and trudges slowly on.

The middle brother’s tall, slim, and keeps a steady pace.

The youngest runs just like the wind, speeding through the race.

“He’s young in years, we let him run,” The other brothers say “Cause though he’s surely number one, he’s second, in some way.”
