I was approached by a bum on the street, the conversation went like this:
bum> can ya spare sum coin?
me> why don't ya get a job?
bum> for what?
me> so you can make some money!
bum> what for?
me> so you can put it in the bank.
bum> what for?
me> so you can earn some interest.
bum> what for?
me> so you won't have to work!
bum> I ain't doin that now!
me> oh.
