I'm A Lightbulb

A woman really hates her job, but doesn't wanna quit, but get fired. So one day, her boss walks into her office and she's on the ceiling. He says "What are you doing?"

She replies "I'm a lightbulb". So he fires her, and when she walks out the door, a blonde woman walks out behind her. The boss asks her what she's doing.

She says "Well I can't work with the lights out."
