Jackson imitating one of his puppies... [VIDEO]

Parker nor I can watch this without laughing ourselves... I guess it's one of those contagious laughs. Jackson just kept imitating the puppy over and over. I couldn't get the longer video to upload; that one is definitely better. I will keep trying, but in the meantime, this one is cute too! (I finally got it to upload using Google Video, but it's not clear... I'm not satisfied, so I'll try to find another way to add it...)
