When the water in the ground Turns a strange shade of brown,      Call the doctor. When water below Has a bright orange glow And you want to know Just why that’s so,      Call the doctor. When the grass that you grew Turns a bright shade of blue And you view your shoe; It’s now a new, blue, hue, too What do you do?      Call the doctor. When the water you drink Burns a hole in the sink And you stop and think Why, water shouldn’t be pink Now, it starts to stink --- Then quick as a wink you’re out on the brink ‘Cause you just can’t think ---- Of a word that rhymes with aquifer. So ----- You call your shrink     and have a talk wif’ her And what’s the shrink think?      Call the doctor.
