From a former employee...

Two hours into my first day of work as a Wal-Mart greeter, an ugly woman came in with her two kids. Hearing her swear at them, I said, 'Good morning, welcome to Wal-Mart. Nice kids, are they twins?' The mom answered, 'Hell no, they ain't twins. The oldest one's 9, and the other one's 7. Why would you think they're twins? Are you blind or stupid?' I replied, 'I'm not blind or stupid. I just couldn't believe someone slept with you twice. Have a good day, and thank you for shopping at Wal-Mart.'
My supervisor said I probably wasn't cut out for this line of work!
