Great one from gilles...

 A young man went into confession crying, and told the priest:

"Forgive me father for I have sinned".

"What have you done?" asked the priest.

"A few weeks ago I went to the library. I remained there until closing time and when I was about to go home, rain started pouring down. It was so intense I had to wait in the library.

I had waited for a while with the librarian, a young attractive single girl, then one thing led to another, and I ended up sleeping with her". The man stopped talking but kept weeping.

"Well don't cry, it's a sin but it is not that bad. You should say 5 Hail Mary's and it will be forgiven". Said the priest.

"But it doesn't end there" the man kept sobbing. "a few days later my elderly neighbour asked me to help her with her computer. Her husband was hospitalized and she couldn't send an email to her son. I went there and fixed the problem, but when I was about to leave, rain started pouring down. It was really stormy and I had to wait. One thing led to another and I ended up sleeping with the old lady" the man cried.

"Oh dear well that makes it harder indeed, but still - you should say 15 Hail Mary's and you will be forgiven" Said the priest.

"Oh I'm afraid the worst part is still ahead" cried the man. "Yesterday I went to the barber. I was his last client that day. As soon as he finished and was about to close the shop rain started pouring down so intensely, I had to wait with him. One thing led to another and I ended up sleeping with him as well" the man cried.

"Oh dear, it is indeed worse than I thought" said the priest.

"So what should I do father?" the man asked.

"Well" answered the priest . . . . ."You should get the heck out of here before it starts raining!"
