Oscar's father organized a party where she was supposed to pick her future husband. Her reaction? She first ordered male dress clothes from the best tailor in Paris (her father believed she ordered a gown until she showed up at the party in male clothes), then she started flirting with the female guests (who happened to be her fanclub), and, to drive her point home, invited her soldiers to make them scare away every aspiring fiancee who hadn't run yet.
After the party Girodelle, who was the only one who had not ran away, tried to convince Oscar to marry him, when, out of nowhere, we have this exchange:
The strip of Jeanne confessing her sins to a priest, only to be arrested halfway due having confessed confessed the attempted murder of Oscar.
The running gag of the Black Knight and chandeliers.
Oscar decides to capture him, but needs a special training... And starts jumping from chandelier to chandelier.
The Duchess of Polignac tries to kill Oscar by dropping a chandelier on her, but the chandelier falls before she's under it... Because the Black Knight was on it.
Napoleon shows up to borrow Oscar's dictionary. Why? Because a goat ate the letter 'I' from Napoleon's... Including the word 'impossible', as Oscar points out.
The strip where Marie Antoinette and Du Barry are exchanging Death Glares until a roasted bird falls from the sky. Turns out, the cook has tripped while carrying it...
Marie Antoinette listens Beethoven playing one of his compositions, and compares it to the light of the moon. Beethoven's reaction? Changing the name into "Moonlight Sonata", renouncing to the original name "Lace Panties Sonata".
Another running gag: Louis XVI and his obsession for lockets, for the immense annoyance of all who get involved with it.
In one strip Louis XVI, sad about not being able to dance with Marie Antoinette, is taking dancing lessons from the Count de Mercy when he throws him away with a sumo move. Rather funny and completely out of nowhere due having been published much later after the previous sumo strip.
In one strip at Versailles they were talking on how better refill the Crown's coffers, someone suggests reforming the finances... When Japanese prime minister Junichiro Koizumi shows up from nowhere and declares they'll first privatize the mail service.
Andre's grandmother berating him for letting Oscar get into a duel, until a frying pan swings back and hits her in the head.
Fersen's look when he's caught by the French Guards while he tries to sneak out of Versailles after a secret meeting with Marie Antoinette. His face is silently saying: "Why did I have to run into the only French Guards who don't lazy around during guard duty?!" Just his luck into stumbling in the one French Guards company who never neglected its duty, and recently got Oscar (who doesn't tolerate laziness) as commander to boot.
The reader may not notice it due Oscar berating Alain for not obeying her immediately, but Fersen's "Well, this explains everything" face when he realizes that those are Oscar's men is priceless.
