One of my extremely strange hobbies is writing variations of the last verse of this poem. The posts are lovely, dense and deep, but I have promises to keep, and lines (of code) to write before I sleep, and lines (of code) to write before I sleep. -- The snacks are lovely; tasty-sweet, But I have promises to keep, And hours to fast before I eat, and hours to fast before I eat. -- The chasm is lovely, dark and deep. But you have promises to keep, And years to live before you sleep! And years to live before you sleep.
