Three nuns walking on the sidewalk....

So three nuns are walking on the sidewalk (on the side of the road) and they see a guy on the other side of the street wearing nothing but a raincoat (and shoes/socks). So the guy crosses the street, walks up to the nuns and opens his raincoat, flashing his you know what to them. So the nuns scare up/scream, because his thing was super huge. Like really, really big. One of the nuns screams to the other two nuns:
> go to the monastery as quickly as you can, get a pair of scissors and hurry back to me while I hold him down!

So the two other nuns run to the monastery as quickly as they can, grab a pair of scissors and run back to the nun and the half naked man in the raincoat. So the nun with the scissors asks:
> Where do I have to cut?

The nun, holding the man, gets down on her knees and says:
> Here and here (pointing to the corners of her mouth)
