At college I'd seen my dead frog's limbs twitch under some applied stimulus or other - seen, but hadn't believed. Didn't dream of thinking beyond or around what I saw.

I have to be seen to be believed.

I wouldn't have seen it if I hadn't believed it.

I have to be seen to be believed.

I wouldn't have seen it if I hadn't believed it.

Every time I hear a politician mention the word 'stimulus,' my mind flashes back to high school biology class, when I touched battery wires to a dead frog to make it twitch.
