You can't argue with logic:

Lady: Do you drink beer?
Man: Yes
Lady: How many beers a day?
Man: Usually about 3
Lady: How much do you pay per beer?
Man: $5 with a tip
Lady: And how long have you been drinking?
Man: 20 years, I suppose
Lady: So a beer costs $5 and you have 3 beers a day which puts your spending
each month at $450. In one year, it would be $5400 correct?
Man: Correct
Lady: If in 1 year you spend $5400, not accounting for inflation, the past
20 years puts your spending at $108,000, correct?
Man: Correct
Lady: Do you know that if you didn't drink so much beer, that money could
have been put in a step-up interest savings account and after accounting for
compound interest for the past 20 years, you could have now bought a Ferrari?
Man: Do you drink beer?
Lady: No
Man: So where's your f*****g Ferrari
