A very loud, grossly over-weight, and very unattractive woman walked into Walmart with her two kids, yelling obscenities at them all the way through the entrance.

The Wal-Mart Greeter says, "Good morning, and welcome to Walmart. Nice children you have there. Are they twins?"

The ugly woman stopped yelling long enough to say, "Hell no! They ain't no twins! Oldest one's nine, and the fat one's seven. Why the hell would you think they're twins? Are you blind, or just stupid?"

In a very pleasant tone, the greeter responded, "I'm neither blind nor stupid. I just couldn't believe that you got laid twice."
