SPONGY BRAINS!

One of these brains is infected with mad cow disease (more properly known as bovine spongiform encephalopathy or, in humans, Creutzfeldt-Jakob disease); one of these is not. Since you can't see inside your brain, guess which one is which!

"This is your brain. This is your brain on bovine spongiform encephalopathy. Any questions?"

"Where Your Eyes Don't Go"
by They Might Be Giants

"Where your eyes don't go a filthy scarecrow waves its broomstick arms
And does a parody of each unconscious thing you do
When you turn around to look it's gone behind you
On its face it's wearing your confused expression
Where your eyes don't go

Where your eyes don't go a part of you is hovering
It's a nightmare that you'll never be discovering
You're free to come and go or talk like Kurtis Blow
But there's a pair of eyes in back of your head

Every jumbled pile of person has a thinking part that wonders
What the part that isn't thinking isn't thinking of
Should you worry when the skullhead is in front of you
Or is it worse because it's always waiting where your eyes don't go?

Where your eyes don't go a part of you is hovering
It's a nightmare that you'll never be discovering
You're free to come and go or talk like Kurtis Blow
But there's a pair of eyes in back of your head

Where your eyes don't go a filthy scarecrow waves its broomstick arms
And does a parody of each unconscious thing you do
When you turn around to look it's gone behind you
On its face it's wearing your confused expression
Where your eyes don't go"
