Funny / Ruyi's Royal Love in the Palace

• Li Yu is dumbfounded to hear that in Europe a man can have only one wife and no concubines.
  Li Yu: Only one wife? There's such a thing in the world? Are you joking, Sir Lang?
• Xiyue trying to get Yonghuang's attention so he could be her adoptive son... by waving a treat at him like a dog.
• After Hongli yells at Ruyi for daring to suggest the concept of a man marrying one woman for the rest of his life, Ruyi apologizes then leaves… but not without shoving the stairs he was sitting on to troll him, with a smile on her face. A Ruo runs after her while stealing glances at Hongli in bewilderment. Wang Qin comes by and tells Hongli that he has an appointment, but Hongli tells him to forget about it. Wang is about to leave when Hongli childishly asks him to wait up and push him back in place, then he tells Wang to slow down, sounding like a pouty child talking to his parents.
• After Mei makes fun of Xiyue’s age despite her looks, if you look closely, you can see Jia trying to hide her chuckle behind her fan at this debacle.
• In the scene where Hailan pours cinnabar dust into her pregnancy medicine to fake her poisoning, her actress revealed that red pepper flakes were used to emulate the cinnabar. Suddenly, Hailan’s pained expression as she drinks the medicine becomes funny in a new light.
• A meta example: Wallace Huo's real-life wife Ruby Lin posted on her Weibo that Hongli (played by Wallace Huo) annoyed her so much she had to stop watching. You know you're playing The Scrappy when even your wife can't stand your character!
