A generalized example would "Shrek is bad." "Pop Shrek is bad are."
For any input sentence with an even number of characters the meme statement applies. Since the meme caption itself has an even number of characters? The generalization applies to itself.
Note the words "this statement" in the caption. Your reading seems to have been "a statement". If so then theorem would claim ,"for any input sentence the mene statement applies."
I'm not trying to make you feel bad for being wrong. The fact that you think about difficultly worded problems with interest is good. Most mathematics is wording at heart.
