A woman was unhappy with the way her laundry was done at the local Chinese laundry, so she wrote a note and put it in the bag with the next collection of soiled clothes: 'USE MORE SOAP ON PANTIES!'
She got the clean laundry back, and was still dissatisfied with the results, so the following week she enclosed another note: 'USE MORE SOAP ON PANTIES!'
The Chinese laundry man became very annoyed, and when her clean laundry was delivered, it contained a note from HIM: 'I USE PLENTY SOAP ON PANTY!!! YOU USE MORE PAPER ON ASS!!'
