X chromosome, xenophobia, x-ray, xylem
yacht, yak, yam, yank

Two chromosones got together, and one asked the other,
“Where’s your partner?”
“You mean my X chromosome?”
“ Oh”
“Y sometimes you lose some chrom.”
“And then you win-some.”
“No chrom-o-some.”
“Oh.”

Hee hee…I made up this joke. Can you tell?
Hey gals, I got desperate.Now to the rest of these nasty words:

I developed xenophobia while stationed abroad,
I’m ashamed to admit it, please forgive me, God.
It developed while x-raying a 1000 yr. old Mormon
I swear his veins looked like a part of a xylem.

And now the next batch…

yacht, yak, yam, yank

The captain of the yacht groaned at his cargo
Cause his yak needed yam, it was a trade embargo.
So he steered to Portugal , where the yam grows wild
There he yanked it out; now on the deck it’s piled.
