It is so funny...whenever the Domino's comercial comes on or any other comercial that has a door bell that sounds like ours he will run to the door and bark! lol But the hillarious thing is that some TV shows and movies that have diferent sounding door bells he will NOT even blink an eye at them lol. He knows the EXACT sound and pitch of our door bell and will act accordingly!!. :lol

yep cosby is the same way
