My Bride Is a Mermaid/Funny


 * Tons of these (such as the entire finale), but episodes 7 and 8 take the cake, with the rivalry between Lunar and Sun actually starting a war, which is resolved with a suitably epic sing-off. Then throw in Saru, who pulls off the most epic use of A Storm Is Coming ever. The whole deal is topped off with the revelation that Maki was not attacks by Lunar's bodyguards.
 * Mawari and the rest of the school's female population storm the school during Sun and Lunar's singing contest. They stop when Mawari sees a crazy fan.
 * "I will calm everyone down with the Mermaid Lullaby!!Lalee-Lo!! Lalee-Lo!! La Lee La Lee La Lee LOOOO!!"
 * Bonus points for Sun's facial expression and dance while singing it.
 * Episode 5. Nagasumi runs into the girls changing room to the tune of an old fashioned Enka ballad.
 * Anytime Nagasumi swoons over Masa-san.
 * Bob & Michael. Srsly, where'd Lunar find those guys?
 * From the DVD special, Ms. Sun's English lessons.
 * Fact: Mer-people are afraid of cats.
 * This troper would argue that episode 14 in its entirety is a Crowning Moment of Funny.
 * Nagasumi gets a love letter.
 * Young San and Kai playing house. San imagines it as a Yakuza house while Kai imagines it like a submarine docking for repairs.
 * "Shibazaki-sensei is... ON MATERNITY LEAVE!"
 * Kai's Oh Crap face after his helmet broke.
 * Sun's attempt to cure Nagasumi by throwing a spear at him.
 * Pretty much every time Lunar's Dad is on screen:
 * Most of Episode 10 is an Affectionate Parody of Terminator 2: Judgment Day and Total Recall. Hilarity Ensues.
 * Lunar's Dad choosing to exit the school premises by lowering himself into a burning dumpster with a thumb's up held above his head.. Even his exit is manly.
 * Lunar's dad in drag.
 * Sun hitting Lunar and then Kai with volleyballs without even trying.
 * Sun imitating other people's laughs.
 * Furiyo dressing up as a human girl named "Brittany".
 * Sun and Lunar turning an all-out gang war into a dance party.
 * Nagasumi shifting into permanent Hokuto no Ken Mode at the end of the series.
 * One episode has Nagasumi drinking a potion to increase his popularity, causing all the girls in the series to see him as what they're ideal man would look like, including Mawari seeing him as a defenseless grade schooler and his mom just seeing Masa.
 * Sun agrees to pretend to be Lunar's boyfriend to help her prepare for a soap opera role. Cue her shifting into a more musclebound, macho persona and taking the term "beard" a little too literally.
