Instead of well known lines one could use his own story with some figures, combined with a fictive word.

For example: tree_eating_5surlap_on_bear (with "surlap" as the fictive word)

Somewhere you just (try to) draw a tree with a mouth, which is eating 5 question marks (representing the fictive word), standing on a bear.

However, I personally prefer mixed incoherent characters and numbers.
