So, I've really wanted to know this since ever, but I kept forgetting to ask someone in the legal profession who could appraise me of the facts. Now T-Rex of the robustly entertaining Dinosaur Comics has answered my query! I recognise no higher authority in the world of jurisprudence.
My question was: can you put a legally-enforceable 'haunted house clause' in your will? You know, like, you can have my money, but you have to all spend one night in a haunted house!
So awesome. I totally wish I could hire T-Rex as my lawyer. Case dismissed, bitches! Heh.
