Blonde Joke

A blonde, a brunette, and a redhead all work for a construction crew. One day, they were on their lunch break, sitting on a beam thirty stories high. They all note that they've had the same lunch for as long as they were on the job. They agreed if they opened their lunchboxes and found the same lunch, they would all hurl themselves off the beam.

The next day, the police are investigating the scene where the three women fell. When the police asked the husbands of the women, the brunette and the redhead's husbands both said, "If I had known, I would have given her something different." However, the blonde's husband said, "Don't look at me, she packs her own lunch."
