I quote this movie regularly. It is one of my fondest wishes to turn annoying customers into a flea, a harmless little flea. Then put that flea in the box, then put that box in another box, then mail it to myself. And when it arrives? (maniacal laughter) Smash it with a hammer.

I have however, considered poisoning them as an alternative. As I have recently relabeled my poisons there is little chance of ending up giving them extract of llama.
