I think it would be more fun and personally rewarding (albeit probably immoral) to get away with any lie you told. Identifying any lie you hear will most likely only teach you things you wish you didn't know.

Proverbs express common-sense truths.
Riddles, on the other hand, can be either questions with a
double meaning, or conundrums/enigmas. In either case, they leave
the recipient guessing.
