They're hours of fun for OCD people too. You can count them, line them up by color like little histograms (or rainbows for you artsy types), eat them in a particular color sequence, turn them all so the little m's are aligned, peel off the shells,...they ought to advertise on "Monk".
Or with the right boards you could use them to play checkers, Chinese checkers, parcheesi, Aggravation, go, Othello....maybe even chess or Trivial Pursuit if there are enough different colors. Marbles? - maybe, but not for long. Got no board? - play Lite-Brite.
