Is this a bong-apple?

I saw this book in the Ravenna Third Place:



Is that an apple that has been made into a bong? Is this book trying to tell me that people who make bongs out of apples are bad people?

Uh.

First of all: making an apple bong seems like a smart good thing to do. It's easily compostible! Hell, we should all be making apple bongs!

Second of all: Okay, if that's not a bong, I still don't get it.
