What is a funny trope that never gets old?

For me personally, I will never get over (intentionally) poorly drawn expressions/reactions. I sit and laugh for several minutes every time. Like when the art is normal overall, but suddenly there comes a panel that completely throws me off and it’s hilarious.

For example, The Empress’ Lipstick. My gawd her expressions are priceless. Or Villain With A Crush.

On the flip side, overly-detailed expressions when there normally isn’t. Like Love Advice From the Great Duke of Hell.

I have other favorites but this trope is the one that keeps me going.
