I found this on tumblr today:

The text above and below reads:
"SOMEONE WENT TO A STAR TREK CONVENTION IN THE 1980’S AS SPOCK AND KIRK’S PENISES I AM NOT MAKING THIS SHIT UP
THEY PERFORMED SPIRK THROUGH INTERPRETIVE DANCE."
I remember making this screencap for
the Fanlore page. Wonderful to see it being re-discovered again and again.
And speaking of memories….Memories (or the lack of them) is one of the many reasons for
Fanlore to exist. I watched the skit on videotape with my friend Sandy in the 1990s…I know this because she wrote a post to
Virgule, the slash mailing list describing our glee and joy and hysteria. An email which I found 20+ years later tucked away in a folder. But in 2011, when someone asked me about the Dancing Penii, I had no memory of the skit. Or ever having watched it. The image must have been too powerful to hold in my memory. So I began researching in order to add more history to the Fanlore page. And that's how the screencap and Kandy's description of the skit found its way there.
