A medical doctor, a lawyer and a programmer debate whether it's best to have a wife or a girlfriend.

"Easy", the lawyer starts, "a girlfriend comes without any legal obligation, you can have a lot of fun together but when you get enough of her, you can just leave her without any trouble"

The physician objects: "That can only come from a man who never truly loved a woman. Your wife is not just someone who you have fun with, she is you bastion of calm, your ever-loyal partner, the completition yourself. Clearly, having a wife is better"

Both now look at the programmer who remained silent throughout the debate.

He cleans his throat and than says: "Both. You need both. You can tell you wife you're with your girlfriend and you can tell your girlfriend you are with your wife. And then, you can finally code in peace.
