I really love the smart aleck tee-shirts too, mostly because that was the kind of stuff I wore in college and now that I'm in a corporate office it isn't permissible anymore.
But I can live vicariously through my dog!!
I'm afraid my "stockpot" yorkie is going to be a bit more difficult to dress once he gets to full size though. The little rain jacket and hoody I bought him don't even fit anymore, and I've had him a week!
