Yeah, I remember the first time I watched CatDog.
I was about 7 and it was a warm summer afternoon and I was eating this huge bar of Cabury's chocolate that a family friend gave me (she's was babysitting me and was about 17). Anyway, I was flicking through the channels (we had Austar) and all of a sudden I saw this little blue mouse and this cat and dog put together and my 7-year-old mind was like: "Awesome!"
I watched three episodes and then fell asleep. I also finished the entire chocolate bar which later gave me a stomach ache I'll never forget, even 9 years later.
