Something I am thankful for that starts with the letter "Z" is........

Zebras. Zephyrs. Zippers. Zeal. Zzzzs. Zen.

Zoology...because I love animals...which brings me full circle back to A for Animals. :D

Zapp Brannigan (What? I can't love the guy just because he's a huge jerk, mysoginist, and - wait...)

Zoo

The number zero because it's like a starting place.

Zebra's They are my favourite Animal's

I am thankful for zoohs.

Zeal of the human spirit ^^
