Hanging out with the Bates

The only way this sentence on the home page Yahoo! TV makes sense is if the family’s name is Bate:

But it’s not. The family’s surname is Bates. If you hang with them, you hang with the Bateses. (Since Bateses is a little difficult to decipher — even though it is the correct plural — a better solution might be to use “the Bates family.”)
