I once had a spider in my house I called Clarence. The first day I saw him I said to myself, 'okay, if you stay on the ceiling then fine. As soon as you come down I'ma kill your ass'.
After a week, Clarence had remained on the ceiling. He moved from corner to corner a lot, but never came down. He even killed a fly or two, which was nice.
Then about a week and a half later he was nowhere to be seen. I didn't take much notice, until late one night I saw him sitting on the handle of the fridge. I went to bed, then when I woke up the next day he was nowhere to be seen. I never saw Clarence again.

But he did leave me a going away present, a fly glued with web to my ceiling. I know he was probably just trying to say 'thank you', but murder is pretty damn illegal and I'd rather not have people thinking I'd committed the crime.
So, FJ... What's the best way to dispose of a dead body?
