Ben 10 has moved in with me

Two years ago Cole bought himself a Ben 10 watch with some of his birthday money. The child wore it EVERYWHERE we would let him. After about a year the stinkin child took it into the shower and it would no longer work. He still continued to wear it and would every once in awhile tell me that it needed new batteries. I would remind him that he took it into the shower so it no longer worked. With some allowance he went to the store and bought the new Ben 10 watch but it just wasn't the same and he continued to wear the old one. Well the other day he took the watch to Grandpa and he changed the battery and lo and behold now the watch works. Cole has had it on his arm non stop and insists that you call him Ben 10. If you call him Cole he will correct you and only answer to Ben 10. He is such a nut.
