The Little Blue Door

The trick to getting Farley's teeth brushed these days is singing potty humor songs such as "Row, Row Row your butt" (to the time of row row row your boat)

Row, row, row your butt gently down the pee,

Merrily, merrily, merrily, merrily life is but a dream. 

Row, row, row your butt gently down the pee,

If you see some poop float by, don't forget to wipe. 

Not classy but it does the trick.
