Dastardly ideas for Dirty Trick

[RumpinRufus]

For a while I've thought making a character that uses Dirty Trick would be really fun, and now I'm trying to brainstorm good ideas for how to pull off some dirty tricks.

My ideas so far:
Throwing whiskey in the eyes
Pulling shirt up over the face
Cutting the belt to drop the pants around the ankles
Kidney punch

So, what other ideas are there for how to pull of a dirty trick?

A weapon hit behind the knee.
Slashing the clothes of someone.
Slashing the forehead(it doesn't do much damage but it bleed a lot)

A little refluff but maybe learning a technique similar to chi were you disrupt internal stuff when you hit someone.

[Flame Effigy]

There's always the good ol' throat punch and pocket sand.

Beside those, sucker punches, shin kicks, and foot stomps are always good.

[Secret Wizard]

Puke on someone's face (sicken, blind).
Scream into their ears (deafen, shaken).
Shining light off a polished blade (blind, dazzle).
