Hard to believe that Lucy was so easily fooled by the green lightbulb. It shouldn't have just been her hands and Ricky and Fred's faces that were turned green. Everything should have had a green tint to them. Moreover, I can't help but wonder why Ethyl didn't notice the green tint everyone (and everything) had. Apparently she didn't notice. Ethyl never once commented on it.
Oops. That should be "Ethel" not "Ethyl". My bad.
