Oh, now I'm truly disgusted with myself. I loved Electric Company. I remember that part now that you mention it, but I wouldn't have remembered what name they used. It was years after I'd learned of Tom Lehrer in college that I realized he'd been poisoning my mind since first grade with the L-Y and Silent E songs. (He does have this thing for poisoning, after all.)

"No right turn. No left turn. What do you do?"

The current equivalent, Between the Lions, is pretty good also. I see it more often that I would like at 7:30am, as it's just before Sesame Street.
