Here's a tweaked version of the joke:

Once upon a time, there were three competitive horses: Speedy, Streak, and Dotty, living on a farm and always up for a race.

One day, they decided to have a friendly race. With the farmer as the starter, they heard the familiar "On your marks, get set, GO!"

Speedy shot ahead like a lightning bolt, leaving Streak trailing behind. Dotty was quite a distance away.

In the homestretch, just as Speedy was about to clinch victory, Streak suddenly stopped running.

Puzzled by Streak's sudden stop, Speedy turned back and asked, "Why'd you stop when you were so close to second place?"

With a grin, Streak replied, "I thought Dotty could use a little more 'spotty-taneity'!" 🐴🏁😄

Remember, it's always good to spread positivity, even in a race!
