Oh, I agree--the car commercial (I think it's for Hyundai) is hilarious, and I love the mastercard one too!! The sprint one was a riot, and there's a commercial for some kind of flea stuff (can't remember what it is), and the scientist guy goes "from the lab" and there's a labrador sitting on the table--hilarious!! There's also another car commercial where the girl starts out with the puppy, and goes through like 3 boyfriends, and always sticks with her dog--cute.
I have noticed that a lot of commercials have pets in them now--probably the majority of them, even if the dogs or cats are just in the background.
Oh--I just thought of another funny one--it's for a Bissel or something, and there's a JRT bouncing around--they even show him bouncing out of the sunroof of the car
