I posted that joke here last month
Here's another "clean" one:
The Blonde and the Snow Plow:
A blonde driving a car became lost in a snowstorm. She didn't panic however, because she remembered what her dad had once told her; "If you ever get stuck in a snowstorm, just wait for a snow plow to come by and follow it."
Sure enough, pretty soon a snow plow came by, and she started to follow it. She followed the plow for about forty-five minutes. Finally the driver of the truck got out and asked her what she was doing.
She explained that her dad had told her if she ever got stuck in a snow storm, to follow a plow.
The driver nodded and said, "Well, I'm done with the Wal-Mart parking lot, do you want to follow me over to K-Mart?"
