A blonde sees a brunette standing in the middle of the highway.

The brunette keeps saying, "88, 88, 88..."

The blonde calls to her as the cars and trucks wizz past, "What are you doing?"

"I'm counting cars," comes the reply. "Want to help?"

"Sure!" says the blond. She walks out to the middle of the highway to the brunette and starts saying "88, 88, 88..."

All the time the cars are dodging the two woman. Then a big semi drives by and runs over the blonde.

The brunnette walks down the highway, picks a new spot, and starts muttering, "89, 89, 89..."
