As said, I have spent time with both.
My best memory is sitting with David out back Gold’s Venice in his car. His GIANT dog was in the back seat and he was slobbering all over the back of my head as David jammed him and his brothers’ latest music on the stereo.
That one song, “War With the Weights”, was among them.
David was literally singing/screaming along, fists clenched ... “War ... with .. the weights!”
(Or sitting in a restaurant and they were trying to mix a protein shake with a portable mixer they’d built. Kid you not, protein powder was flying everywhere and they were howling just like they’d do it their movies. It WAS NOT an act. I was just sitting there, thinking, This is AWESOME!)
They were hilarious guys. But clearly David was the more “with it” of the two.
To me, it’s painfully obvious Peter’s (I believe some used to call him Pee Wee, as he was the smaller of the two) situation is legitimate mental illness. It’s not an act. He’s gone off his rocker.
As others say, I, too, imagine he will sink even deeper now that David’s gone.
Totally sucks.
They treated me very well the times we hung and were colourful, beyond funny and, yes, intelligent (in their own way).
At one time they were seriously impressive physical specimens, as well.
