I was perusing an etymological dictionary, and, like an 8-year old, I immediately looked up the word “penis.”  I haven’t changed at all.  I remember when I was younger I would look up the word “sex” in every dictionary I  could get my hands on (if I had a time machine I would go back in time and stuff child-me in a locker).  Anyway, “sex” was always next to some picture of a “sewing machine.”  That led to years of confusion.

As for the fact…well, the etymological dictionary told me that the proper plural for penis is “penes.”

I would hate to be the guy that had a reason to make the plural of that word.  Or would I love to be that guy… 

That’s all I got to say about that.
