Are you not from the United States? Here, it's very common to find all of those things in one "super store". Walmart, Meijer in the Midwest, Fred Meyer in the Pacific Northwest, no doubt others in other regions of the country...

I'm not from the United States and it's not strange to find those things in one store in many places, but it's also weird to find them as the three things on a shopping list. We could play this game all day but I'm not going to shift from:

a) those three objects together are going to sound weird in pretty much any situation

b) regardless of the effectiveness, mixing genes from a list of things that sound like they would never mix under natural circumstances in any other way than a lab sounds weird

It's not a "game", and there's nothing at all "weird" about those three things being on a shopping list if you're going to Walmart or Fred Meyer.

If you needed antifreeze, why on earth would you not put it on the shopping list for the place that has it?

To the pedantic this would not appear to be a game but that would miss the point.

I'd like a parrot, a gun and a pack of cigarettes.

To the person who doesn't really have a valid point, it might be worth trying the tactic of pretending it's a "game", but that would be about as effective as a cat attempting to bury a turd on a hardwood floor.

Cat, turd, hardwood floor - poor effort, that's not a weird combination. I'm sure you might get the hang of it if you keep trying.

Now, if you don't think some triplet is weird, that's subjective (as I would hope anyone would understand and admit) but to try and claim that:

a) some objects together aren't weird, or

b) those objects together aren't weird

and

c) to make either claim means the claimant doesn't have a valid point

that would really be akin to producing a turd into the conversation, logically and rhetorically. Nice of you to bring up tactics during a discussion about what constitutes a game though, that's worthy of a chuckle.
