We've had this thing for years (2 anyway) and where our terrier will destroy 99% of her toys, for some reason she treats her "Mr. Bill" doll with love.  I love the ridiculous Mr. Bill yelp - ohhh, noooooo...  Some times it drives the husband batty and he'll put it on top of the fridge for a few days.  Wait.  Maybe THAT's why we still have it?
