"Stupid"- A bro's Creation

Over the weekend, a big argument broke out in my household that led to charges of "I'm going to sue you, i'll see you in court!" What was all the hubbub about you may ask?...my twins were disagreeing about the copyright ownership of an idea they had for a book they've both been writing comics for over the last few years. The characters name is "Stupid"...this is seriously highly intellectual stuff friends. "Stupid" never seems to learn his lesson, theres alot of falling, farting, eyeballs popping way out and a nuclear button that he keeps pressing. I told the boys to gather all the evidence they had and present their arguments to me this Wednesday...I would be presiding over the case and would issue a verdict on who had the actual monetary rights to this idea. A few hours later they were friends again and cowrote another book....but this time they added their new company name to the bottom..."A bro's creation". I did get a sneak peek at their oral arguments they had been working on and their evidence...basically outlining what parts of "stupid" were their idea and which parts were their brothers...I think Darbys depiction amounted to Coopers owning nothing except the wart on "Stupids foot"...Coopers depiction gave Darby ownership over the entire right foot, way more generous...it would have been a hard case to decide. This whole thing in itself could be a book I'd write myself but then I'd have to contend against "a Bro's Creation LLC" in court one day, not worth it!!
