Eddy drove fast.
"Skidding is bad for tires," he thought.
"But it's fun!"
Eddy jumped over the dirt hill.
Then he skidded far.
"Yes!" Eddy cried.
Everyone cheered.
Eddy drove off again.
Zippy followed.
They both skidded.
Suddenly—Pop!
"Oh no!" Eddy cried.
"My tire popped!"
"Ha-ha!" Zippy laughed.
"Your tire—" Pop!
"Ugh! My tire popped too!"
Mr. Grill rushed outside.
"What's going on?" he cried.
"We were skidding," Eddy mumbled.
"Our tires popped," said Zippy.
Mr. Grill frowned.
"Come with me," he said.
Mr. Grill found new tires.
"No more skidding," said the teacher.
"Do you know why?"
"Yes," said everyone.
"It's bad for your tires!"
