This is the same method Apple officially recommended in their help for choosing a secure password—the example they gave was “Tnf,tfws95” (“That’s not flying, that’s falling with style”) followed by the year of Toy Story’s release (where the quote is from). I agree that it’s an excellent combo of passphrase and obfuscation. Unfortunately, their documentation now[1] gives the same kind of example that XKCD points out will be exceedingly difficult to remember correctly.
