I miss the default IKEA instruction to have two people for building even the tiniest piece of furniture.

How many people do you need to assemble a BILLY bookshelf?

Three!

One to read the manual.

One to be instructed by the first on how assemble it.

One to break up the fight when the first two get into fisticuffs over step 4 in the manual.
