Spontaneous Human Combustion

This is one of those very rare occurrences that we would ever see. It appears that Ann Coulter began to smolder while she was in the middle of a rant about liberal comedian Al Franken. She kept on talking like nothing happened.

I don’t know what to make of this story for I did a Google search on - spontaneous combustion “ann coulter” - and came up with some results (about 26) that were not talking about this event. Could this be a stunt to increase her book sales or is this just a coincidence?
