These are very common in Canada still and anytime I see one I point at it and make the same joke “Looks it’s Vent Reznor” and my girlfriend has never once laughed. Oh well.
I mean, compare "Spam" the Monte Python sketch against "Four Candles" (the Two Ronnies). Four Candles is hilarious the first time you hear it, but Spam only really works on repetition which is why the sketch iterates internally so it's repeated within itself.
On the other hand while "Mastermind" (also the Two Ronnies) is hilarious if you understand the cultural context, you can get "Spam" with no context whatsoever, it's funny because they keep saying "spam".
All to say - maybe the repetition works eventually? Ask again after a decade of marriage :D
