A Portuguese brain surgeon heard a lecture in New York about
damage to frontal lobes rendering patients free from anxiety. So the brain surgeon went home and destroyed connections to frontal lobes in a bunch of paranoid schizophrenics, and they no longer were upset by their hallucinations. So some US guys copied him. And their
patients didn't give a sxxx where or when they sxxx.
I wonder if I could find that guys's name. I'll try.

I'll be dipped in doggy doo-doo. I found it on the first try. It helped that I guess right on the guy's name - Moniz.
More than you are likely to want to read, but anyway:
