Fold AA on the river to a loose/passive?

[marand]

Villian is very loose and very passive. (50/8/0.5 after 100 hands)
I have not seen him get out of line, but maybe I haven't been paying enough attention /images/graemlins/smile.gif

Obviously only the river is interesting.
The river is just terrible, both a flush and straight just got there.

Can you find a fold against a loose/passive here?
(I obviously couldn't bring myself to do it.)

I couldn't find a fold their either. Often you lose; but often enough even a loose passive has bet the river because he has one pair. Philosophy seems to be to bet it out when a scare card comes because you won't likely raise and they would call your bet anyway. I've tried this out myself a number of times and it's pretty effective in this spot. So, I call and expect to lose often but not often enough to make a fold right.
