Every morning and every night I squirt sea-water up my nose, as the doctor told me to.
I sing a jaunty song as I do so:
The wise man squirted water up his nose (x3)
As the doctor told him to.
The water shoots up and the bugs flow down (x3)
So squirt some water up your nose.
But as of yet the efficacy of this treatment is unconvincing.
I sneeze. My nose runs. I am, basically, unconvinced.
I'll keep going till the can runs out of water, but I can't promise that I'll buy another.
