Gabor's character says that the Bois de Boulogne is "where all lovers come". Incorrect! In fact, since at least the '70s, le Bois de Boulogne has had a notorious reputation as the "red light district" of Paris.

It is unclear if this title made it in the Hexagon, and how this inaccuracy would have been translated.
