A group of nuns are standing around talking when one goes "I found a pile of dirty magazines yesterday!"

All of the nuns gasp, except for one who goes "hehehe"... then another goes "I found a condom yesterday!"

And all the nuns gasp, except for one who goes "hehehe"...then the same nun says "but there was a hole in it"...that one nun gasps, and the rest go "hehehe!"
