A car full of Irish nuns is sitting at a traffic light in down town Dublin, when a car full of rowdy drunks pulls up along side them. "Hay , show us yer teets, you bloody penguins! " shouts one of the drunks.
Quit shocked, Mother Superior turns to Sister Mary Immaculeta, "I don't think that they know who we are; show them your cross."
Sister Immaculeta rolls down her window and shouts, "Piss off ya fooken' wankers before I come over there and rip yer balls off!"
Sister Mary Immaculeta then rolled up her window, looks back at Mother Superior, quite innocently, and asked, "Did that sound cross enough?"
