He really is a little smasher, Gill, and having now seen the pics of him I have to agree he does look more of a Disney than a Memphis. You'll just have to save that name for number four.
Maybe Vegas remembers playing too much with Dallas when you first brought him home and thinks that's why you kept him, so he doesn't want to fall into the same trap twice.
I look forward to hearing more tales from the Wonderful World Of Disney, I'm sure this is just the calm before the storm. Then again, I have heard talk of calm , well behaved Cocker pups, I've never believed it though.
