the really offensive thing about shaky eggs is that they all sound identical. Now if you are a fiddler, you can distinguish yourself with your approach to phrasing and ornamentation. If you are a guitar playing, the way you harmonise is part of your own unique musical fingerprint. If you are a drummer, the worlds of melody and harmony aren't open to you, so choice of timbre is one of the few ways that you can put your own stamp on the music being made. So it follows that shaky egg abuse is a key pointer to small-brainedness - any thinking percussionist will make his own shakers - it's really easy dammit!
