Alphabet Soup

A friend once told me to write a poem that
Began with the letters, and it
Could rhyme or not, so I
Did the best I could, and made sure
Each line was
Funny and fit the theme. It sounded
Good, and I worked really
Hard to make sure
It made sense, because
Just in case it didn't, I didn't want to
Kill the cool idea, which I
Liked a lot.
Many times I did get stuck, but it did
Not stop me from going
On, I just took a
Pause and asked myself a
Question about what the next line could
Represent, and
Slowly but surely I got
Through the entire alphabet
Until the
Very end,
Where an occasional hard word like
Xylophone would have to work, but
You know what? Guess how many letters are left?
Zero.
