| But he was determined, Then change two, |
| then three more, The others went home.  |
| As year followed year. He dug out the   |
| flow chart And strangers would comment, |
| Deserted, alone. "Is that guy still     |
| here?"                                  |

| the console The room was cluttered Of   |
| hunger and thirst With core dumps,      |
| source listings. Next day he was buried |
| "I'm close," he muttered. Face down,    |
| nine edge first.                        |
|                                         |

| wife through her tears Logic,           |
| deduction. Accepted his fate. "I've got |
| it!" he cried, Said "He's not really    |
| gone, "Just change one instruction."    |
| He's just working late."                |
