I haven't done it yet, but...
Recently a friend and I went through an old abandoned building downtown, and in a pile of junk I found an old alarm bell- you know, the kind with the 8" diameter bell that hangs on the wall, usually meant for fire alarms and the like. I took it home and discovered that it works just fine.

My plan is to hook it up to a timer set to go off at about 3am, and hide it under my ex-wife's front porch. But before I do, I'm going to strip it down and sandblast the bell, then paint it a nice bright cheery yellow and put a smiley face on it (complete with "Have a nice day" written around the rim). I can just picture the bitch's face now when she finds it in the middle of the night...

Edit: Nicky, I like the way you think. I may have to investigate a better grade of timer, just so I can do that. I also thought of hooking it up to a motion sensor so that it would only be active for the night (keeping the timer idea), and would go off whenever a cat went by or something, which would make it very sporadic...
