Mama bear, papa bear, and baby bear were having a great time chasing vacationers in a car as they were visiting Yellowstone National Park.

"Daddy?"

"Yes, Baby Bear?"

"I think we could be doing a better job of scaring these vacationers."

"But Baby Bear," Mama Bear injected. "What more can we do?"

"Maybe we'd have more of an effect on them if we got out of this car and started chasing them on all fours!"
