This one's pretty much a given, but giving security agents a hard time won't do you any favors. In fact, being rude or uncooperative is a surefire way to delay your journey.
If a TSA agent asks you a question, give them direct and straightforward answers. This is not the time to joke about terrorism or bombs unless you want to find yourself detained — or worse, miss your flight.
Don't argue about trivial matters either, like whether or not your bottle of body wash really is under 3.4 ounces. You might think a security agent is in the wrong, but they have the power at this point. Starting an argument with them is going to get you nowhere fast.
If you're respectful and follow the directions you're given, you'll speed things up for everyone.
A great carry-on bag can be a major help.
