Two Irish nuns were sitting at a traffic light in their car when a bunch of rowdy drunks pull up alongside of them.
“Hey, show us your boobs ye bloody penguins!” shouts one of the drunks.
The Mother Superior turns to Sister Margaret, “I don’t think they know who we are. Show them your cross.”
So Sister Margaret rolls down her window and shouts, “Screw off ye little fookin’ wankers, before I come over there and rip yer nuts off!”
Sister Margaret looks back at Mother Superior “Was that cross enough?!”
