On hearing this clip of Al Gore turning comedian on Davenetics Blog, I figure this should be part of the presidential campaign. An open mic spot. It's perfect.
On a serious note, this is a clever tactic. Making your audience laugh (especially at yourself) is engaging and disarming. Al Gore goes on to discuss what the audience can do to reduce their impact on the environment- it's not the most seemless of links between the comedy and tough talk, but hey, that's why he keeps coming runner up.
