As I was riding today, I remembered part of an old WWII era joke I heard one of the old men at the VFW tell.

I always understood the German for horse as Pferd.  I was doing something online and came across Gaul as an alternative.
And all of the sudden the half-remembered punchline of this forgotten joke made sense.  It had to do with riding a Gaul (Frenchie) as if she were a Gaul (horse).

And there you have it.  A joke I don’t really remember that I just figured out after a 20 year comic pause.
