Four priests board a train for a long journey to a church council conference.
Shortly into the trip, one priest says "Well, we've all worked together for many years, but don't really know one another. I suggest we tell each other one of our sins."
They look nervously at each other but nod OK. The first priest says "Since I suggested it, I'll go first. With me it's the drink. Once a year I take off my collar and go out of town to a pub and drink myself blind for a few days. Get it out of my system."
They all look each other again nervously, but the next priest slowly starts "Wellll......with me, it's gambling. Periodically, I nick the money out of the poor box and go to the races. Spend it all! I get it out of my system."
The third, who is really nervous now reluctantly says "This is very difficult. My sin is worse. I take off my collar and go into the red light district, pick out a lass, and spend a week in the saddle. I REEEEAAALY get it out of my system."
They all look at the fourth priest waiting. He doesn't say anything. Then one of the four speaks up "Come now, we've all told our innermost faults. It's your turn." He looks at the others and starts hesitantly "Welllllll..... I'm an inveterate gossip, and I can't wait to get off this train!"
