"Ice Cream Parlor Emasculation" joke

This is a true story, not a UL. Honest.
Years back, when my son was about 18 months old, I, my wife, and the kid
would go out for a hot fudge sundae every week, and split it three ways.
On one occasion, after I placed the order, the nubile young lady in the
local Baskin Robbins asked (with a bright smile that could have been
coquettish or merely polite) "Would you like your nuts wet or dry, Sir?"
I immediately choked. This was, after all, exactly the kind of line
every male dreams of. Then I glanced at my wife, who was glaring back at
me with a crimson complexion. Swallowing hard, I got a grip on my
libido.
"Uh... No nuts," I replied. "No nuts at all."
