>cover slit A, leaving slit B open
>observe single slit interference
>cover slit B, leaving slit A open
>observe single slit interference
>leave both slits open
>observe double slit interference
sounds fine to me. why does this confuse people?

It's not a meme, it's the double slit experiment presented in a way that further highlights the strangeness of superposition, it case double slit wasn't strange enough for you.
If you don't understand the significance of double slit you will dismiss this one as well, because fundamentally they're showing the same principle: superposition.
