I think I have a few more examples that I as a GM would allow:
1. "Ringing the bell" - opponent wearing a helm gets the cartoony added deafened
2. "Pulling a Zorro" - low level mooks with crap Intel seeing their opponent write a Z in their shirt = Dazzled
3. "My one and only weakness!!!" - opponent is weak to fire or lives in low light or dark? Fire weapon in the face should blind them, equally acid for rock, fire for ice, and in general, I believe fire to the eyes should always be accepted. Its a freaking flaming weapon. Shoot, I'll even let it act like a torch.
