Save time, TaxHack. Hit Ctrl+F, put "plink" in the box that appears, and your computer will tell you if the word occurs in the thread or not.

I can see how a teacher could use this technique to entertain the kids and teach about instruments. Have them imitate a violinist and sing "fee fi, diddley." Then play a banjo with "plink plank". Then a flute with "tweet, tweet." And so on till the final bell rings.
