The Pennsylvania Dutch, which as “everybody” knows were not “Dutch” but German folks, had a droll sense of humor according to The Pennsylvania Dutch, by Fredric Klees, 1950. They loved bad riddles:

What kind of stones are found in water?    Wet ones.

On which side does a dog have most hair?  The outside.

Why do farmers build pigsties next to the barn? For the pigs.

Here’s the best one cited by the author:

What is as white as snow, as green as grass, as red as blood, and as black as a hat?   A black cherry!

If your ancestry includes Pennsylvania Dutch folks, this book is a must-read for background understanding.  (Found it on Amazon for $26.00.)
