Thank You For Shopping Walmart

After landing her new job as a Walmart greeter, this sweet retiree I know lasted less than three hours on the job.  About an hour & a half into her first day, a very loud, unattractive & mean-spirited woman burst into the store with her two kids, yelling obscenities at them all the way through the entrance.
The sweet retiree said pleasantly, "Good morning, and welcome to Walmart.
Nice children you have there.  They're twins, right?"
The mean-spirited woman stopped yelling long enough to grunt, "Hell no, they ain't twins!  The oldest one's nine, and the other one's six.  Why the hell would you think they're twins?  Are you blind, stupid or both?"
The sweet retiree replied, "I'm neither blind nor stupid, ma'am.  I just assumed they were twins 'cause I'm sure NOBODY is blind or stupid enough to sleep with you twice!" 
The sweet retiree is now working at TARGET.  ;)  Haaa!
