Dilbert: My brain isn't working at its peak efficiency this afternoon. Common sense says I should go home early to avoid making any mistakes that would be bad for the company. Unless... nothing I... do is important. Boss: Sounds like your brain is back to its peak efficiency.
The Boss points to a wall of circular openings and tells Dilbert, "I borrowed a Japanese work custom - sleeping tubes!" The Boss explains, "No more wasted time commuting. If you keel over from exhaustion we'll just cram you into a sleep tube." Dilbert asks, "Which tube is mine?" The Boss replies, "You don't get a personal tube unless you're employee of the week."
Dilbert: Do you mind if I only work sixty hours this week? I need some rest. Boss: I don't want to set a precedent that your health matters. That's a slippery slope. Dilbert: I might die from sleep deprivation. Boss: Don't ask me to validate your selfishness.
