"Cab Experiment" joke

A blonde and her brunette friend were talking, when the blonde said, "I hate all the blonde jokes people tell."

"Oh, they are only jokes. There are a lot of stupid people out there. Here, I'll prove it to you."

They went outside and hailed a taxi driver.

"Please take me to 29 Nickel Street to see if I'm home," said the brunette.

The taxi drove them to Nickel Street, and when they finally got out, the brunette looked at the blonde and said, "See! That guy was really stupid."

"No kidding," replied the blonde. "There was a pay phone just around the corner. You could have called instead."
