Oh I'm brushing my teeth on top, it's so much fun I hate to stop, but while I'm brushing my teeth and having so much fun, I never let the water run. No I never let the water run. Oh, I'm brushing my teeth on the bottom, cuz I wouldn't wanna say that I forgot em', but while I'm brushing my teeth and having so much fun, I never let the water run.  No, I never let the water run.  Oh I'm brushing my teeth in back, gotta get rid of all the plaque, but while I'm brushing my teeth and having so much fun I never let the water run. No I never let the water run.  Oh I'm brushing my teeth all around, cuz I like to hear the squishing sound, but while I'm brushing my teeth and having so much, I never let the water run. Oh never let the water run.  Nah Nah Nah Nah Nah Nah Nah Nah, I never let the water run.
