[schwza]

that's interesting - i never show a bluff (or a big hand). i'm just too paranoid about giving info away about my hand.

but last night, i did find myself in a spot where somebody showed a bluff on the river, and then ~20 minutes later i check-raise bluffed him with a weak hand, i think partly out of some dumb desire to "get him back." (but then i spiked an overcard and won a big pot - hehehehe....)

maybe one reason people will give action to a bluff-shower is that they know that if they fold there's a chance they'll be shown a bluff, which is painful. letting a non-shower bluff successfully is less painful because at least you won't be confronted with it.
