Taken from Chinua Achebe's book, "Things Fall Apart."
"Yam, the king of crops, was a man's crop."
Wife: What would you like to go with the pot roast, dear?
Wife: But we had yams just yesterday! Wouldn't some asparagus be nice?
Husband: I want yams. With butter and salt.
Wife: Why are you so hooked on yams?
Husband: Because yams are a MAN'S crop!
