I got this joke from a book. This one is good:
It is the day before the wedding and the bride goes to a priest for a confession.
Bride: Father, I've been engaged for three years and am getting married tomorrow, which is way I ask you to forgive my sins.
Priest: Tell me your sins child.
Bride: One day I was at the mall when I ran into a coworker. We just talked and then he invited me over to his new place. I went and then we ended up in bed, you know father, that's because I'm such a pullover...
Priest: Pushover, child.
Bride: Its not just that, the day after I ran into a high school friend and then he decided to show me his new hotel and I went. Then we went to a room and ended up in bed, you know father, that's because I'm such a pullover...
Priest: Pushover child.
Bride: The other day I ran across my boss and he invited me over for dinner. I went over and we ended up in bad. You know father, thats because I'm such a pull.... What's the right word?
Priest: Whore, my child, whore.
