Okay, so there was this car with 4 nuns in it and they crashed into a bus, killing them all instantly. When they got to the pearly gates, St. Peter tells them, if you have ever done anything unholy, then let us wash that part of you with holy water, so the first nun goes up, and she says, "I've seen a penis" so she rinses her eyes out and goes through the gates. The second nun goes up and she tells him she's touched a penis, so she rinses her hands and goes on to heaven. Then the fourth nun runs up and says, "there is no way I'm going to drink the water after she (nun 3) sits in it!!"
I'm prolly gonna go to hell now for telling that...*rolls eyes*
And sorry, it's late and I can't really remember how it goes, but that's the jist of it.
