A doctor, a lawyer, and a biologist are discussing the costs and benefits of having an affair.
The doctor says no one should ever have an affair. It creates too much anxiety and it’s bad for your health.
The lawyer says it’s OK to have an affair as long as you don’t tell your wife. If you tell your wife, she might file for a divorce and it’s bad for your pocketbook.
The biologist says it’s an excellent idea to have an affair and it is very important to tell your wife. If you tell your wife, she will think you’re spending time with your mistress, your mistress with think you’re with your wife, and you can finally get some time in the lab.
