Family story — my father used flat beer to knock me out when I was a teething infant. Apparently I started to develop a taste for the other stuff Dad drank...
One night my parents were invited to my paternal grandparents house for dinner. During the cocktail hour, 3 year old me was wandering around saying “scotch” “scotch” “I want scotch” — my grandpa, operating under your theory, gave me his glass which held bourbon and said, “here Bobby, have some scotch!” Reportedly, I took a swig, got a look of disgust on my face and handed the glass back to my grandad, telling him “Grandpa! That’s not scotch! I want scotch!!!”
My grandmother aksed a very pointed to my father — “How does a 3 year old know the difference between bourbon and scotch?” I still don’t know what the answer to that question.
Oh, that is funny! [As your dad] I’d say you’d jokingly told you that grape juice is also called scotch and hope that there’s not any grape juice around for grandma to test that explanation with :)
And at least he used flat beer and not the bottle to knock you out.
