Sister Mary's Confession

Sister Mary Katherine goes to the church for confession. "Father" she admits. "I'm a horrible person. I've committed an atrocious sin" "Now Mary Katherine" says the Father. "I know for a fact you are a very holy woman. Unburden yourself, and i assure you it can't be that bad" "Father" she says, "I dot wear any underwear" "Sister!!!" Father says. "No underwear?" "Yes, I am ashamed" she says. The Father replies "For your punishment I issue you 10 cartwheels"
