To serve the donut would be to say the donut is. It clearly is not and cannot be that which it is not. “Serving Donut” also imparts some form of deification to Donut.
Donut is not a deity. Donut simply is not. To serve donut is to serve oneself by accepting the utter futility of serving anything for any reason.
Immortality projects or attempts to live past the mere blip of time we have been allotted on the physical realm is folly.
Praise be the sprinkles and the glaze.
