I wish they made those tiny little round white stickers they have inside Apple products out of gold [1]. They keep getting wet and voiding my warranty.
I'm not sure if sarcasm or not, but that's the point. If they got wet enough to 'trip', then enlighten damage could have been done to internal components to void your warranty anyway.
