The new priest is nervous about hearing confessions, so he asks the older priest to sit in on some of the confessions.
The new priest hears a couple of confessions and then the older priest asks him to step out of the confessional for a few suggestions.
The old priest says, "cross your arms over your chest and rub your chin with one hand... and try saying things like, 'yes, I see, and yes, go on, and I understand.'"
The new priest does as he's told and repeats all the suggestions back to the older priest. The old priest says, "Now don't you think that's better than slapping your knee and saying, No shit?.... what happened next?"
