> Now one problem with the "French Cafe" technique is that you can only learn words that the customers use. What if you want to learn other words? Say for example you want to learn to swear in French? You would try ordering something at the cafe, then stepping on the waiters toe or poking him in the eye when he gives you your order. As you are being kicked out you take copious notes on the words he uses.

This is written so compellingly that I almost want to try this approach to learn French swearing.
