UTTIN' ON THE IIIIIIITZ!
The latter role was a comic masterpiece, and for that wild set of facial expressions, grunts, and grimaces alone, he'll be remembered. And it's for that he should be remembered.
Unfortunately, I fear that far too many will think of him as Ray Romano's dad on the execrable Every Loves Raymond, the inexplicably popular sit-com that somehow forgot the "com." Look at the headline from the Yahoo! News piece, by way of A.P: "'Raymond' Dad Peter Boyle Dies in NYC." Not "Young Frankenstein Monster," but "Raymond Dad."
Oh well. Next time I watch Young Frankenstein I'll laugh, as I always do, and that'll be good enough for me. RIP, Pete.
