Actor
Every actor eventually is called upon to act drunk. Most do this by slurring their speech, stumbling around, and perhaps drooling a bit. This is what a freshman drama teacher calls indicating. A better way to appear drunk is to act very, very sober. Walk very carefully, and try not to let anyone see that youre inebriated. This is much more subtle and will register on a level the audience wont immediately recognize.
Cartographer
Mapmakers will often use copyright traps, bits of information in their maps that are purposefully wrong. They might label a body of water Lake Strongbad, for instance, and then examine the next editions of competitors maps to see if the incorrect information makes an appearance.
Landscape Architect
You will often have to create a large presentation for clients, and will spend hours coloring in landscape illustrations with markers. But if you say the drawings are rendered rather than colored, you can charge four times as much.
