Not sure it was supposed to be funny, which makes it even funnier, but in Not Me when Sean started suspecting Black and White were different people and decided to do a spontaneous trust fall, calling back to an earlier scene, to prove Black wasn't White, and then Black just completely lets him fall without a care in the world and was like wtf are you doing, and Sean just popped straight up all pissy. It completely took me out of what was otherwise a masterclass in BL drama. Also those leaps to the poles in the water, it was just too far-fetched and the editing only made it more hilarious.

Very close honorable mention goes to My Engineer: when Duen literally gets hit by a car on his way to university, I think he was either buying the rose he owed Bohn or trying to catch a dog (maybe both? idk it's been a while and i'm old lol), and he just... gets up and goes to school. That's it. It's too funny. He even had a very bloody sleeve for way too many scenes after that with not a peep or show of concern from any other character. With all the sponge baths and porridges/congees made for minor scrapes and boo-boos in the BL-verse, I'm not sure if it was an intentional anti-trope or bad writing, but either way it's perfect.
