Where's your Ferrari then?

 Lady: Do you drink?

 Man: Yes

 Lady: How much a day?

 Man: Three 6-packs

 Lady: How much per 6-pack?

 Man: About $10.00

 Lady: And how long have you been drinking?

 Man: 15 years

 Lady: So a 6 pack cost $10.00 and you have three 6-packs a day which puts your spending each month at $900. In one year, it would be $10,950 correct?

 Man: Correct

 Lady: If in 1 year you spend $10,950 not accounting for inflation, the past 15 years puts your spending at $204,250 correct?

 Man: Correct

 Lady: Do you know that if you hadn't drank, that money could have been put in an interest paying savings account and after accounting for compound interest for the past 15 years, you could have now bought a Ferrari?

 Man: Do you drink?

 Lady: No

 Man: Where's your  Ferrari then?
