Subject: Male logic

This a conversation between a man and his wife. Please note that she asks five or six questions which he answered quite simply, but then she is speechless after answering only one question. l bet this happens more often than not to most husbands out there:

Woman: Do you drink beer?
Man: Yes
Woman: How many beers a day?
Man: Usually about three
Woman: How much do you pay per beer?
Man: $5.00 which includes a tip (this is where it gets scary!)
Woman: And how long have you been drinking?
Man: About 20 years, I suppose
Woman: So a beer costs $5 and you have three beers a day which puts your spending each month at $450.* In one year, it would be approximately $5,400 correct?
Man: Correct
Woman: If in 1 year you spend $5,400, not accounting for inflation, the past 20 years puts your spending at $108,000 correct?
Man: Correct
Woman: 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 an airplane?

Man: Do you drink beer?
Woman: No.
Man: Where is your airplane?
