Batman Slapping Robin

If you didn't get this meme, that's because it's an inside joke about band. F# is the same as Gb.

I know they are the same, that's why I made the "not sure" face... as in not sure why people argue over it so much.
As someone who has always been a musician at heart (but not in practice), I've always seen this topic as somewhat of a ridiculous formality.

I get you. I made this meme because I'm a flute player and I have to deal with these kinds of notes all of the time!
