Wally was a slow-moving, unpopular clerk in a small grocery store.
One Monday morning, Wally wasn’t at work.
A loyal customer asked the owner where Wally was.
The owner said, “Wally doesn’t work here any more.”
The inquisitive customer asked, “Who do you have in mind to fill the vacancy?”
The owner replied, “That’s no problem at all. Wally didn’t leave a vacancy.”
