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.
