Step 1. Mod raws to allow blocks to be made out of body parts and bones, also make Elves produce tears on death and mod them as a building material, like ice currently is (more on this later).
Step 2. Defoliate surrounding area of trees to acquire necessary materials for step 3 (and piss of those Elves)
Step 3. With newly gathered wood create giant wooden middle finger at least 15 z-levels high, that points towards nearest Elven settlement. (Further angering those Elves)
Step 4. Kill Elves that besiege the almighty finger and harvest their corpses.
Step 5. Thanks to previously edited raws, create blocks of elf flesh, supports of elf bones, and masterwork blocks of elf tears.
Step 6. Build a floor of elf-flesh blocks that connect the edges of the surrounding surface to z-levels above the booze.
Step 7. Now that it is not in immediate danger of falling, tunnel down to level with the booze and place the elf-bone supports to alleviate the strain of the z-levels above(physics don't work like that now but you made the supports, might as well use them).
Step 8. Build second giant fist with middle finger out of Elf tear blocks (again facing the Elf settlement), making sure to leave a hollow space for booze and enough space for an epic dinning hall.
Step 9. Store booze in Elven Tear Finger.
Step 10. Create tables, chairs, and mugs from masterwork elf-tears.
Step 11. Allow Dwarfs to enjoy booze in epic dinning hall of Elf tears, once again knowing that you have pleased Armok.
Step 12. Take screen shots of Fingers in Stonesense and post them on forums.
