Yup---My Parents used to listen to Prof' Schnitzel too, and we used to get to the Kutztown Festival every year. Kutztown is only about 1/2 hour from here.i " enchoyed" that! Really an inside joke of sorts, with typical dry PA Dutch humor. I don't know if you've ever heard any of the Professor Schnitzel bits back in the 1950's-60's, but my grandparents loved listening to him on the radio, at the Kutztown Folk Festival, and I think they must have had records of his. He was a PA Dutch standup comedian, if you can believe there ever was such a thing, and that joke sounds like something he'd come up with.
I only know a few Dutch words, but my Grandparents spoke Dutch a lot, and my Dad could speak it good enough to go to "Grundsow" meetings, where they weren't allowed to speak anything but PA Dutch. And Mrs Bear's Dad used to teach PA Dutch in Night School at Quakertown High School.
