monkey trap

Do you know how to catch a monkey?  You put peanuts into a jar that has a mouth large enough for the monkey to get his hand in.  Once he has the peanut he can't get his hand out and he isn't willing to let go of the peanuts in order to get his hand out.  Michael is my monkey.  He put his hand into my box top box and wouldn't let go of the box of baggies that I had in there.
