Haiku of the week

I have been challenged to use "tubes" as the subject of my haiku this week. I happen to have a good story that this gives me the opportunity to tell:

Tubes Tied Test
Fertilization:
occurs in the Eustachian
or Fallopian?

Answer
If you carefully
read your Biology test,
answer "oviduct."

Problem
Don't pick the answer
that first says "tube," not reading,
or embarrassed be.
(and possibly have a bad earache!!)

This is based on a true story of my Biology AP class in high school. Having gotten back my test and going through the answers, I noted that I'd gotten wrong one that I knew I had correct. I raised my hand to ask why I'd gotten it wrong. Thankfully, before the teacher called on me, I learned my mistake and lowered my hand (chuckling to myself). I had checked "eustachian tube" for where fertilization took place, not being careful and intending to have picked "fallopian tube," which was not an option because "oviduct" was the correct alternative answer. I did still get an A on that test, however. :)
