Can we get the joke, without the breed? I'm curious now, and I didn't see it.
and I can't speak for everyone, but I don't think I'd sweat the reference to pitbull too much. You didn't mean anything by it, and I think we are all a little sensitive in today's enviroment to pitbull references (I know I am). That being said, when I'm with close friends or family members, I use the stereo-type to make a point or a joke. Personally, I'd say no worries. Just don't let it happen again, or we'll sick a poodle on you!
Oh, and Lucky, I know you were making a point with your first post, but it still made me crack up looking at that picture! I hope that was intended as well!
