Fish And Tadpole

One day, a small fish sees a tadpole. He wants to compete with tadpole, see who can swim faster.

"Are you dare to take up the challenge?" asks the fish.

"Why not?" says tadpole.

So they compete, and finally fish wins.

Tadpole goes home and cries to mummy, "Mummy, I lost to fish in swimming competition."

"My dear, wait for another few days and you can go challenge the fish again."

After few days, tadpole's fore and hindlimbs start to grow out. He then goes to see the fish, "Want to have another competition?"

"Why not? " says the fish.

This time, tadpole is able to swim by using freestyle (the fastest of the four official styles) with his limbs, so he wins the competition.

The fish goes home crying, "Mummy, I lost to tadpole in swimming competition."

"My dear, wait for another few days and you can go challenge the tadpole again."

After few days, the tadpole has turned into a baby frog. The fish comes to challenge him again, "Want to have another competition?"

"Why not? " says the baby frog.

This time, the baby frog can only swim with breaststroke (frog stroke - the slowest of the four official styles). So the fish wins the competition.
