You can't trick it. Every moment has value. Then plot line. Audience is effected by emotion, not intelligent. Audience is caught up in emotions, not ideas.
Every scene look for two guys in a ring.
The answer is, you have to make everything that happens meaningful. Once you decide what the guy is doing and what he is feeling, you got to stay on it. Get the right laughs at the right time. But a reflection of life. Scene ain't worth anything unless there is conflict.
