One of podcasting's unspoken rules flies in the face of what you were told in grade school: Don't try so hard.
We've all heard broadcasters and podcasters who work really hard at being funny but fall flat in the process. The goal is to not be one of those people. Your most memorable, funniest moments will be unplanned and natural; your most groanworthy moments will come when you try to force a joke or snarky comment. The lesson? Don't force it.
