How you will pay

One dismal rainy night, a taxi driver spotted an arm waving from the shadows of an alley halfway down the block.
Even before he rolled to a stop at the curb, a figure leaped into the cab and slammed the door.
Checking his rear view mirror as he pulled away, he was startled to see a dripping wet, naked woman sitting in the back seat.
- Where to? he stammered.
- Union Station, answered the woman.
- You got it," he said, taking another long glance in the mirror.
The woman caught him staring at her and asked :
- Just what the hell are you looking at, driver?
- Well ma'am, I noticed that you're completely naked, and I was just wondering how you'll pay your fare.
The woman spread her legs, put her feet up on the front seat, smiled at the driver and said :
- Does THIS answer your question?"
Still looking in the mirror, the cabbie asked :
- Got anything smaller?
