Sir Anthony says while listening to Greensleeves, "Omnia vincit amor," to which Henry VIII translates as "No one can resist love." The literal translation is "Love conquers all." The correct Latin translation for Henry VIII's response would be, "Nemo potest resistere amorem."
Greensleeves was not written by Henry VIII, but was first registered by Richard Jones in 1580, about 30 years after the events of this episode.
