"Insert Tab A into Slot B."
"Where's Slot B?"

"What do we need Panel D for?"
"I think it's to rest Housing M on."

"I think you've counted them wrong. See, this size is Screw R and this size is Screw S."

"Because this was designed in Hell. Next time we need furniture we are getting ready assembled."
