Personally, I think the best ways to get rid of a bible study at your home is to: get the neighborhood kids to make as much noise as possible during the "study" time. Pay them to do it. It's worth it.
The second way is to find something that has as odious a smell as you can find. Keep it in something that will seal tightly, like Tupperware or some other top brand of plastic container. Human execrement is always good, since that's what they're studying in the first place. Dog execrement is also good for the same reason.
Or, you could get some iron filings, small ungalvanized iron nails, staples, stuff like that and just before the meeting pour a small amount of battery acid on the iron stuff and hide it under the sofa. Be careful with this one. Battery acid is pretty hefty (sulfuric acid) and you especially need sulfuric because you have a use for the sulfer in it. It reacts with the iron filings and gives off H2S, which smells exactly like rotten eggs (mainly because that's what gives rotten eggs their stench). You only want to generate a LITTLE of this gas, mainly because it's poisonous - another similiarity with what's going on in your home.
OR, you could try this time-tested technique: cut the bastard off until the study stops. Not just on study night, but EVERY night until the study is gone. Primitive but effective. That should get the message across about how much you detest this study in your home. "No Peace, No Pu...." well, you know..."No Peace, no piece." Gads, that's good. I wish I'd thought of that,,,,,,no wait, I DID think of that. Try it and report to us here. We'll be waiting. No Mellon testing while studies are going on. No pointing to the sky with the toes until the torture stops.
Ain't this house half yours? Don't you deserve no respect here? Ain't he supposed to respect you like you was he himself? Did he even bother to AXE you if'n it was OK to have a study there? Take over. Make him see what it's going to cost him. Is he using this to "reach out" so next you know, he'll be gone every night that's not a meeting night spying on someone else's bidness? You want to get started down that loooong and lonely highway? Stop him NOW while the stopping is good.
Watcha think everyone?
