Obviously the succubi do not exist. The problem is that they act as if they existed. The last week I went to sleep after an exhausting backgammon game and a succubus came in through the window to ask me for a few cents. I panicked and started to whimper in a corner while the succubus ate the carpet. When I opened my eyes again, the succubus had disappeared and the carpet was all bitten. Damn succubus!
