I recommend putting your dog on a leash when you're walking through a parking lot.
If you don't do this, you may end up with a dog with cat pee all over his head - then you'll be sorry.

As I was leaving work yesterday a big dog (no collar, no leash) chased a fat cat under a car and then up a tree. The cat was stuck on top of a high stump, the dog was below enjoying the thrill of the chase. The cat peed all over the dog's head, but the dog kept on lunging after the cat.
The owner of the dog was leisurely walking through the parking lot with walkman on, seemingly oblivious by the whole thing.

That reminds me of an Aztec Camera song that used to send me into girlish hysterics!!!

Love the lyric, "I see you crying, and I want to kill your friends."
