The following story conflicts with Amos's statement: A doctor, a lawyer, and a physicist are having a drink, and the topic of conversation is: whether it is better to have a wife or a mistress. A wife, says the doctor: you are less likely to get various diseases. A mistress, says the lawyer: if it doesn't work out, you don't have the agony of a divorce. A wife *and* a mistress, says the physicist: then, when your wife thinks you're with your mistress, and your mistress thinks you're with your wife, you can do *physics*.
