"88, 89..." joke

There was a brunette standing along side a busy road chanting "88, 88, 88, 88..."

A blonde came up to her and said, "That looks like fun, can I try?"

The brunette said, "Sure."

So the blonde chanted, "88, 88, 88, 88.."

"Well," said the brunette, "that is fun. But what is even more fun is if you say it in the middle of the street."

So the blonde said, "OK." and stood in the middle of the street. "88, 88, 88, 88-" BAM! she was run over by a car, completely flattened.

Along the side of the road, the brunette began to chant, "89, 89, 89, 89..."
