I recognise the quote every time. But I do not plan on learning the individual numbers of any of the xkcd strips. Recognising the quotes is enough for me.
(Un)fortunately for you, human memory and cognition is weird.
927.
So by the time you reach this sentence in comment, the number 900, which is Yoda's age in the original Star Wars, plus the number 27, which is 3 cubed, as well as the name of the "27-club", will have appeared three times if you count my previous comment.
That number, 927, should stick out in your brain as being the number for the XKCD strip about standards.
It's possible that the mnemonic, and the repetition is enough for that number to permanently lodge itself in your brain. Or not.
