Assuming we have the same words file (the number of entries match), this contains a lot of hard-to-remember variants. For example every name occurs in there as "Jack" and as "Jack's". It is definitely not the list of simple words used by XKCD 936 (dictonary size 2^11 == 2048).

For the sake of discussion, a script of mine generated this alternatives from the same 64 bits of randomness:

adzes rights Macumba's staleness's
AU's mastoscirrhus seel Bremerton's
Abgangszeugnisse Sollstärke blumigen Synthetik
17244702336126568816

cpprKpTOYLaG
uH25bi602OO
dLl%M4Aw.ZI
?bwto5p5Zs
y°USK8Tüöq
g-ßa+j6ög3bv

Decide for yourself if you're better at remembering the spelling of "mastoscirrhus" or "adzes" (or was it "adzes's") or a shorter random jumble of characters.

I added another wordlist based on Ogden's Basic English containing a bit over 2000 words. Example output:

There are lists created specifically for this usage.
Just take the diceware list or one language spcific one.

The diceware list contains too many obscure entries for my taste. YMMV.

We can agree that /usr/share/dict/words is usually not the best candidate.
