Man, I can see it now....a sea of chihuahuas!!! Okay, I have to admit it...I had to look up to see how to spell chihuahua!! A little boy at my school was telling me he got a new dog. I asked what kind, and he said it was a "choo choo wa" I made up questions to ask him just so I could hear him say "choo choo wa" So, Chopper, have a blast with all of the other "choo choo wa's"!!! You're adorable.
