Google Code-in

A hard one, or may be not. You know that canned laughs in American sitcoms? Is there a way to reliably detect them? The task consists of doing the research; see if there's something out there that does it, or any technical document that explains how it could work. Or, if you are even more inclined, figure out a way yourself. Then, if we feel that we have enough information to do it, we'll create a new task that consists on the implementation.
