Things that after all these years, still get you in a good way, either in comedy, action, romance, lewdness, etc.
>character is politely declining or denying he/she are any good at doing something
>he/she is doing the exact same thing in an amazing way, like saying "I'm not strong" but lifting a ton of shit with one hand
>comically strong and dangerous character that never fights, even the other stronger/calm characters think twice before angering him/her
>if he/she is involved it is awesome, but could easily break the whole story
Extra points for never even lifting their voice or having a crazy face until an actual fight, and even then the character is calm.
