An ugly arrogant woman walked into a store with her 2 kids, yelling at them.
The store clerk pleasantly said, "Good morning ma'am and welcome. Nice children, are they twins?"
The ugly woman stopped yelling and said, "Hell no they are not, one is 9 and the other is 7. Why the hell would you think they're twins, Are you blind, or just bloody stupid?"
The clerk replied, "I'm neither blind nor stupid ma'am, I just can't believe someone would screw you twice,"
