Two Irish nuns were sitting at traffic light 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 ’em.

Mother Superior turns to Sister Immaculata, “I don’t think they know who we are – show them your cross.”

So Sister Immaculata rolls down her window and shouts, “Screw off ye fookin’ little wankers, before I come over there and rip yer balls off!”

Sister Immaculata looks back at the Mother Superior and asks, “Was that cross enough?”
