A housewife, an accountant
A housewife, an accountant and a lawyer were asked ''How much is 2 plus 2?''

The housewife replies: ''Four!''

The accountant says: ''I think it's either 3 or 4. Let me run those figures through my spreadsheet one more time.''

The lawyer pulls the drapes, dims the lights and asks in a hushed voice, ''How much do you want it to be?''
