What's the opposite of a tapeworm?

Because that's what I had for the last week or so. I had some sort of stomach bug that wasn't letting me keep food down, so while the down side was not being able to eat, the plus side was an automatic diet. Just when I was getting used to having applesauce as a meal, my boss made me a plate of roast chicken and vegetables and very sweetly told me to eat it for lunch today. Lo and behold, I discovered that I am back in business, baby.  Hallelujah.

Now, does anyone know where I can buy a tapeworm?

Trust

Trust that there is a tiger, muscular

Tasmanian, and sly, which has never been

seen and never will be seen by any human

eye. Trust that thirty thousand sword-

fish will never near a ship, that far

from cameras or cars elephant herds live

long elephant lives. Believe that bees

by the billions find unidentified flowers

on unmapped marshes and mountains. Safe

in caves of contentment, bears sleep.

Through vast canyons, horses run while slowly

snakes stretch beyond their skins in the sun.

I must trust all this to be true, though

the few birds at my feeder watch the window

with small flutters of fear, so like my own.
