Fountain script?

Does anyone have a random fountain script ? Looking for something to put on a fountain probably accessed via a dialog that does random stuff to the player if they drink it , cure, restore, damage, polymorph, poison, disease, etc . . .

I used this in my first module. Maybe it contains something that you could use?
