| It's something unattainable | |
| That you can't live without | |
| And now the unexplainable | |
| Has you riddled with doubt | |
| Things began, things decay | |
| And you've gotta find a way to be okay | |
| But if you wanna spend the day | |
| Wondering what it's all about | |
| Go and knock yourself out | |
| Why we're put in this mess | |
| Is anybody's guess | |
| It might be a test | |
| Or it might not be anything | |
| To be too worried about | |
| But if you're still in doubt | |
| Go and knock yourself out |
