Walmart Greeter...

A very unattractive, mean actin' woman walks into Walmart with her two kids.
The Walmart Greeter, asks "Are they twins"?
The ugly woman says "No, the oldest one, he's 9 and the younger one, she's 7. "Why?........ Do you think they really look alike?"
"No", replies the greeter, "I just couldn't believe you got laid twice"!
