Completely random strings of words can be hard for me to remember, but something like, "the {adjective1} {animal1} {verb} the {ajective2} {verb2}" would be much easier for me to remember because the words relate to each other ways I already understand.
I expect we can get some fairly high entropy from just simple schemes like this.
However, the length of the password can be a real pain if you have to type it often, even once a day.
You could get about 8 bits per animal, and 5 bits per hand-written verb / adjective / place (32 choices per category). So that's about 7-10 words you need in the frame.
You could get decent entropy with: the {adj} {adj} {animal} {verbed} the {adj} {adj} {animal} from in {place}. That's 5+5+8+5+5+8+5 = 41 bits.
