Recall the ten Major-System pegs for 20–29 — the /n/ decade. Can you name all ten in order and picture a story that links them?

Every 20s peg starts with the /n/ sound (2); the second sound is the unit digit (0–9), so 20 = n·s = nose, 21 = n·t = net, and so on.

20 nose · 21 net · 22 nun · 23 Nemo · 24 narr · 25 nail · 26 nacho · 27 nuke · 28 knife · 29 knob

Example story (make your own if this one doesn't stick): A giant nose gets tangled in a fishing net held by a nun, who scoops up little Nemo and hands him to a jester (narr). The narr hammers a nail clean through a cheesy nacho — just as a nuke flashes on the horizon. A knife slashes the smoke, and everyone dives for the door knob to escape.
