The blonde girlfriend
One day a blonde was scratching her boyfriend’s car with a ruler. He came out and told her that rulers are used for measuring how long things are. Not for scratching cars. In the morning he went to wake her for breakfast and had noticed that the ruler was under the bed. He said to her, ” I thought I told you your’re suppose to use a ruler for measuring how long things are.” She replied, ” I know, I wanted to measure how long I slept.”
