I thought that sentence was completely unnesscessary, and I was very close to removing the paragraph above too. There is no need to mention a time when Squiddleward posted an explanation. That can be in the Notes section, or not said at all. It may have something to do with the meme, but it is unnessecary to mention. (Besides, it doesnt matter if someone thinks its "SpongeGar" or not. Its not like were talking about the names of famous Scientists.)
I wont do it again, but I would at least suggest it moved to a 'Notes' section.
