“One Cuban young woman complains to another. ‘He lied to me! He told me that he was a luggage handler! It turns out, he’s nothing but a neurosurgeon!'”
This fits perfectly with the characterization of Cuba in Daína Chaviano’s excellent El hombre, la hembra, y el hambre [Man, Woman, and Hunger], in which an economics professor becomes a butcher (maybe we’d all be better off) and a literary translator becomes a prostitute, both in order to escape hunger.
The joke (and a detailed explanation) are here. [HT: Marginal Revolution]
