Maybe it was video games that they weren't allowed? There was one episode a few seasons back where they were playing video games, but I haven't seen a game system in the house since. The pool table (they have a pool table right?) and the pool are a step in the right direction but these guys tend to have a high level of intensity and Spike is trying way harder than they need to to set the stage for explosions. i.e. no TV, but truckloads of booze? That's another reason trashing the house is so boring by now, it's predictable beyond belief.
