I'll comment. In re the video: If a modification is permanently attached to a structure and it becomes a part of its function, the change becomes the property of the owner. For example, a tenant moves a partition or changes some plumbing, etc; the mods are the property of the landlord. So our video is nothing more than a confession to destruction of someone's property, notwithstanding the injustice of cheating the contractor. Perhaps the contractor should have invoked his rights and put a lien on the entire property, making the owner pay up or get it sold out from under him.
Now for the Roundup water balloons: If this did happen, then the homeowner has your confession to taking the law into your own hands and might call the fuzz and then haul you into small claims court for a new lawn. Just commenting on what's here; there is likely a lot more information to consider.
