Imagine, if you will, that you have just won the lottery/sold some drugs/inherited millions in Nazi gold and you never have to work another day in your life. How would you quit your job?
There is an actual chocolate factory I pass every day on the way to work. I would go in, commission a 10 pound bag of chocolate dicks, and go into work as usual. I'd then go up to my boss, put the bag on his desk, and say "I have millions of dollars now. Eat a bag of dicks."
Said bag could also be great fun in a retirement home or nunnery.
