A young brunette goes into the boss's office and says that she suffers great pain whenever she trades.
"Impossible," says the boss. "Show me."
She takes her finger and brings up a chart and screams in agony.
She pushes her finger to put in the amount of the trade and screams, slaps the entry key and screams.
Everytime she touches the keyboard makes her scream.
The boss says, "You're not really a brunette, are you?"
She says "No, I'm really a blonde".
"I thought so," he says. "You have a broken finger."
