What doesn't work...
You know what doesn't work? When you're experiencing computer problems, and your friend says "what's up" and you express your frustration with your computer, and perhaps, in a fit of (understandable) hyperbole you say "god I hate computers" and at that moment your friend either sarcastically suggests a typewriter, or tells you they'll remind you of this comment when you're later on raving about your newest piece of technology.
Here's the thing. Sarcasm, aside from being the lowest form of wit, is probably the most dangerous form of wit to someone who's frustrated. In a moment when I very much want to punch someone in the teeth, you would do well not to volunteer.
