Historical curiosity. This answer to "Why did the chicken cross the road" can be interpreted two ways: 1. it's obvious, absurdist humor 2. it is a pun on the phrase "other side" meaning the after life.

Betcha never thought of the second interpretation!

I did personally think of the second interpretation after many years. Prior to that I thought it was just something that sounded like a joke but wasn't actually funny, or maybe some meme whose origins I didn't understand. Once I thought of the second interpretation, I assumed that's what the joke must have been all along. So I was slightly surprised to read your post there.
