A man goes into the confession booth at church. "Forgive me father, for I have sinned". "What is your sin, my son?" asks the priest. "Well, about a month ago I was in the library until closing time, and when I wanted to leave it started to rain very heavily and didn't let up. After some time, me and the librarian lost our patience and... well... partied all night, if you catch my drift". "That is bad but not horrible, my son" said the priest "if it is a one-time slip, God will forgive you". "That's just the thing" said the man "about a week ago I helped my neighbour fix her shutters, and when I wanted to go home it started raining heavily and... well... you know, all night long". The priest remains silent. The man covers his face in his hands and starts sobbing "What should I do now, father?" "WHAT SHOULD YOU DO?!?" screamed the priest "You should buy a fucking umbrella!"
