How do you get a nun pregnant? Dress her up as an altar boy!
A little boy wants a bike for Christmas really badly, but the kid is a real bad seed, and he knows it. He writes a letter to Jesus. "Dear Jesus, if I get a bike for Christmas, I'll be good for a whole week." He thinks about it, crosses out what he wrote, and says, "I can't be good for a whole week, I'll be good for five days." He crosses that out and writes, "I'll be good for four days." Then he thinks again and says, "Can't do that." He gets down to one day and says, "I can't even be good for a day." Then in frustration, goes in his mother's room and get the statue of the Virgin Mary, wraps it up in a blanket, puts it in a paper bag, throws it in the closet and says, "Dear Jesus, if I don't get a bike for Christmas, you'll never see your mother again!"
Four nuns are in line to go into heaven. God asks the first nun if she has ever sinned. She says, "Well, I've seen a penis." So God puts holy water on her eyes and lets her enter. He asks the second nun the same thing and she says, "I've held a penis," so he puts holy water on her hands and lets her enter. Then the fourth nun skips the third nun in line and God asks why she did that. The 4th nun replies, "Well, I need to gargle it before she sits in it."
Two nuns were riding their bicycles down the street. The first nun says, "I've never came this way before." The second nun says, "Yeah, it's the cobblestones!"
