"We are all electric creatures floating in the electric sea of this electric universe."
- Walter Russel
"Winny and I lived in a house that ran on static electricity. . . .If you wanted to run the blender, you had to rub balloons on your head. If you wanted to cook, you had to pull off a sweater real quick."
- Steven Wright
