Why Isn't the Line Moving? – From the Blonde Files
At a store, a Blonde lady stood in line waiting to pay for her items.
Three men stood before her in the line. After 15 minutes she realized that the line wasn't moving at all.
She shouted at the cashier, 'Is this line going to take all day long?'
The cashier replied, 'Please step aside ma'am and come here. You are standing behind three mannequins.'
