Ha! When looking for a title to the keyboard entry, I used an online rhyme generator. The following apparently rhyme with "keyboard:"

keyboarded, pegboard, seaboard, bodyboard, larboard, inboard, freeboard, greybeard, aboard, cupboard, fretboard, outboard, lapboard, headboard, overboard, footboard, bombard, regard, baseboard, Bedford, dartboard, Reynold, chessboard, duckboard, sailboard, elbowed, breadboard, record, leotard, shipboard, starboard, fiberboard, Lombard, buckboard, Bernard, graybeard, sideboard, seabird, moldboard, Gaylord, dashboard, paperboard, wallboard, tailboard, Bernhard, retard, washboard, signboard, westward, petard

I like so many things about this, including how (a) "keyboard" rhymes with every other "-board" word except just plain "board"; and similarly (b) a "greybeard" and "graybeard" totally rhyme but a regular "beard" does not.
