1. Argue that marijuana should be legal. Being right will give you an immediate advantage. This argument won't guarantee success by itself, but you can't win without it. There has never been a documented instance of someone looking intelligent while arguing that marijuana should be against the law.

2. Try not to say anything completely insane. It's clear that Calvina Fay has come unhinged when she claims that, "about 60% of everybody out there using drugs is involved in abusing children." Such statements will cause viewers to associate your position with derangement. Similar lapses can be observed at other points in the debate when Calvina is speaking.

3. Be the last person to talk. Notice how Rob Kampia concludes the debate with a series of correct statements. Speaking last will help prevent viewers from becoming confused by your opponent's ideas. If the moderator offers your opponent the final word, draw attention away from their comments by transitioning between the following series of facial expressions: surprise ? skepticism ? amusement.
