The nightgown delivered instead of thorns
Teodorico Raposo spends years performing extreme devotion so his rich, sanctimonious aunt in Lisbon will make him her heir, and she sends him to Jerusalem to bring back a holy relic. He makes a crown of thorns from a bush, but in Alexandria his English lover gives him her nightgown with an obscene inscription, and the two paper parcels get swapped. At the ceremonial unveiling before the aunt and her clergy, the nightgown comes out, and he is disinherited on the spot while her fortune passes to the church.
