Canadian Dr. Seuss at our house

I thought I'd let you in on a recent reading of "Dr. Seuss's ABC" at our house. Rob was reading it to Meredith as follows:

"Big A, little a, what begins with A?
Aunt Annie's alligator, A, A, A"

"Big B, little b, what begins with B?"
(etc.)

"Big Y, little y, a yawning yellow yak
Young Yolanda Yorgenson is yelling on his back"

"A B C D E F G
H I J K L M N O P
Q R S
T U V
W X Y and.... ZED!"

"Big Zed, little zed, what begins with zed?
I do. I am a Zizzer Zazzer Zuzz, as you can plainly see."

(addendum by Rob)
"That's a silly one Meredith. It doesn't rhyme."
