I prefer the Richard Pryor variation. "If you had two more inches of d!ck you'd find some new p***y here!"
Chew Chew or Mit Mit. (+10 points for whoever gets the reference) I do enjoy Star Wars references. When I get dogs they will be named Chewy and Wookie.
Our dog is named Chewbacca and we call him Chewie. When we first got him as a tiny puppy, the back of his head looked exactly like Chewbacca's. <a href="http://picasaweb.google.com/treymcglaun/Pets08/photo#5129212875850540098"><img src="http://lh4.google.com/treymcglaun/Ry6f71JuZEI/AAAAAAAAJng/KVFDbir45BU/s400/IMG_2735.JPG" /></a>
My parents had a miniature weenie dog named Chewy. He was the best. I have a turtle named Yaddle. (obscure Star Wars name)
