You're definitely overthinking this. "Butt" getting back to the nipples, it's not that they grew hair. The deal is Fox should have been nipped in the bud. Before he blossomed into a bum (which is an english term for butt - at least on Benny Hill).
At least you didn't say he should have been nipped in the "butt". We would have had to call a contractor for something like that.
How about calling for a contract? Can we do that? You know, make him an offer he cant refuse...
