Zuska had a botfly
living in her leg.
(In truth, I do not lie.)
Came a little egg,
rolled off a 'quito's back,
down the little snout
into the hole its sack.
There twould not come out.
It had a little tube,
where it got its air;
and blew it in a fugue--
raising Zuska's hair!
Came out a worm one day,
color of slick white.
From then we cannot say.
Except when it's night,
a new egg is begot,
waiting for a ride--
plus some of Zuska's lot--
to now in you reside!
