On the impracticality of a cheeseburger.
Further reflection revealed that it's quite impractical--nearly impossible--to make a cheeseburger from scratch. Tomatoes are in season in the late summer. Lettuce is in season in spring and fall. Large mammals are slaughtered in early winter. The process of making such a burger would take nearly a year, and would be wildly expensive--requiring a trio of cows--and demand many acres of land. There's just no sense in it.
