Butts on Stools

In today's Dinette Set, Burl's ass perches atop a stool, while the astute reader:

• Recognizes that the artist made the exact same joke 4 months ago.
• Remains just as appalled now as they were 4 months ago to learn that Burl is a Manager.
  
• Is impressed enough by the "Windows on Mac" joke that you have to assume the artist's intent was not what you think.
• Can't understand the sign regarding sick days and vacation days. Are we to believe there's a company that allows people to use sick days as vacation days? In America?
