Louis Wu and the Snip/Snip

So my wife asked me about Louis surgery. I explained as best I remembered.

Reminds me of this time, years ago, while driving around Cambridge, MA, near that upstart school Harvard University (founded 1636. Bah. Boston Latin School rules!!). I was a kid then, in the back seat. My dad and his girlfriend were in the front. We drove past some construction barriers, and on them were painted the words VAS DEFERENS in big block letters. They laughed, that inside the baseball adult laugh. I asked them what was so funny, but they wouldn't tell me.

Later, as I studied, I finally reconstructed the pun on my own.

"There's a vas deferens between men and women."

At least, I think that was it.
