DONUT DAY AT THE OFFICE

Part 6 Bob: Donut spheres? Enameled happiness? Has anyone noticed who isn't eating donuts right now? Are we about to form a blue ribbon commission here?

David: Bob, don't you see what's happening? While we fight over which of us gets the candy, our co-workers, who are working by the way, are missing out on these delicious chemical donuts. Meanwhile, our friend Alison will be left out of the mix, as will Winfred, who is back in the hospital. What about our custody and shipping people who are relegated to the basement world? Once again, they won't get freebies and they are the ones doing the real work. They're not even allowed here in our break room because we don't want their greasy hands in our microwave. The only good reason for rules here is to protect the donutless among us. Donut laws are no good unless they address inequalities that would otherwise not even be considered.
