Two Irish nuns are sitting at traffic lights in their car when a bunch of rowdy drunks pulls up alongside of them.
"Hey, show us your tits, ye bloody penguins!" shouts one of the drunks.
The Mother Superior turns to Sister Immaculata and says, "I don't think they know who we are - show them your cross.".
Sister Immaculata rolls down her window and shouts, "Screw off ye little fookin wankers before I come over there and rip yer balls off!"
Sister Immaculata turns to Mother Superior and asks, "Was that cross enough?"
