For most people, a light bulb is semiotically sufficient to indicate a sudden inspirational thought, but when Al gets started on global warming...
Woe unto those downwind from the fallout of his brainstorms! Is that some kind of Angry Left gang sign Al is flashing with his left hand? Hmm... , I wasn't at the presentation today, but was Al proposing a nuclear winter to offset global warming? And, oh yeah, is it just me or does this picture remind anyone else of Dr. Strangelove?
