A crackpot with styrene eyes

The story:

I've always heard it that way; it doesn't sound like "eyes" but
I'm so convinced he said "crackpot" and "styrene" (artistic
license on polystyrene?) that I picture the only thing that a
crackpot might have made of styrofoam...big, round eyes from
the craft store. I visualize it so clearly (don't you now, peering
in your window?), I hear "eyes" even when it's clearly not
there...
