Three blondes are attempting to change a light bulb. One of them decides to call 911: Blonde: We need help. We’re three blondes changing a light bulb. Operator: Hmmmmm. You put in a fresh bulb? Blonde: Yes. Operator: The power in the house in on? Blonde: Of course. Operator: And the switch is on? Blonde: Yes, yes. Operator: And the bulb still won’t light up? Blonde: No, it’s working fine. Operator: Then what’s the problem? Blonde: We got dizzy spinning the ladder around and we all fell and hurt ourselves.
