A Christian girl in love with a Jewish guy agrees to change her religion. She goes to a Rabbi for instruction.
Rabbi: "You will learn how to light the candles, keep two sets of dishes, keep a kosher home, and a few other simple things."
Girl: "That sounds easy to me. I can do that."
Rabbi: "The last thing is, you must go to a mikva."
Girl: "Mikva, what's that?"
Rabbi: "It's a pool of water and you must immerse yourself completely for a few seconds."
Girl: "I'm sorry, I have a phobia about putting my head underwater. I'll go in the pool but I can't put my head under water. Will that be all right?"
Rabbi: "That will be okay. You will be mostly Jewish but you will still have a 'Goyisha kup'!!!"
