A car full of Irish Nuns are waiting at the traffic lights in Downtown Dublin, when a bunch of rowdy drunks pulls up alongside them.
"Hey, show us yer teets, ya bloody penguins!" yells one of the drunks.
Quite shocked, Mother Superior turns to Sister Immaculator and says "I don't think they know who we are; show them your cross"
Sister Immaculator rolls down her window and shouts
"p*** off, ya fookin' little w******s, before I come over there and rip your bleedin' balls off"
"Sister Immaculator then rolls up her window, looks at Mother Superior quite innocently and says
"Did that sound cross enough?"
