The “salami bologna” is an extremely obscure reference from a (very) old Popeye episode. I have yet to meet anyone who has seen it and still remembers it (most have Alzheimers by now). It must have had some pop culture significance to the writers that I am oblivious to, because all their other references are downright mainstream.
Keep the mysteries coming! There is a room full of Ellery Queens 🙂
