Two Irish nuns were sitting at a traffic light . . ..
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 tits, ye bloody penguins!" shouts one of the drunks.
The Mother Superior turns to Sister Margret, "I don't think they know who we are. Show them your cross."
So Sister Margret rolls down her window and shouts, "Screw off ye little fookin’ wankers, before I come over there and rip yer nuts off!"
Sister Margret looks back at the Mother Superior and asks, "Was that cross enough?!"
