Put some cheese on a plate with a little sign that says, "Cheese for the mouse". Let him eat from the cheese plate for 8-10 weeks. After the time limit is up, replace the cheese with crack cocaine and a little sign that says, "Thank you for your patronage". He'll be so used to the cheese that he won't even think twice about it (plus he'll appreciate the patronage thing and it will give him a sense of well-being), he'll just eat it. Continue this for another 4 weeks. After the 4 weeks, don't put anything out except for a picture of the crack cocaine. He will leave your house immediately to work the street corners sucking cock for more crack. VIOLA!!
