How to pronounce "dentistry"

I call it "The Toothbrush Helmet."  

So my toothbrush helmet is

recommended by zero  out of 10 dentists,

and it definitely did not

revolutionize the world of dentistry,

but it did completely change my life.

Since then, I've carved out this little niche

for myself on the internet

as an inventor of useless machines,

because as we all know,

the easiest way to be at the top of your field

is to choose a very small field.

To me that's the true beauty

of making useless things,

because it's this acknowledgment

that you don't always know what the best answer is.

And it turns off that voice in your head

that tells you that you know

exactly how the world works.

And maybe a toothbrush helmet isn't the answer,

but at least you're asking the question.
