I came to Casablanca for the waters

- What in heaven's name brought you to Casablanca, Rick?
- My health, Louis. I came to Casablanca for the waters.
- The waters? What waters? We're in the desert.
- I was misinformed.

I love this Casablanca dialog. This is the kind of lie that has an ironic half-smile and says "no, I’m not answering your question, you’re being invasive".

But I hate pretentious lies, lies from people that are clearly trying to fool you.
