It was an unusually cold night, and it had been snowing continuously for hours. An off-duty towtruck driver came across a vehicle that had skidded off the road and was partly submerged in a drainage ditch.

Spotting an attractive young lady standing nearby, the driver stopped and offered his assistance.

She smiled gratefully, as the man began to hook the towtruck to her car.

Making conversation, the driver said "You know, you're the third pregnant lady I've helped out of this ditch tonight."

The trim young lady was puzzled and a bit insulted as she said "You're mistaken, I'm not pregnant!".

Winking at the young lady, the driver retorted "You're not out of the ditch yet".
