The doctor, after an examination, sighed and said, ‘I’ve got some bad news. You have cancer, and you’d best put your affairs in order.’ The woman was shocked, but managed to compose herself and walk into the waiting room where her daughter had been waiting. ‘Well, daughter, we women celebrate when things are good, and we celebrate when things don’t go so well. In this case, things aren’t well. I have cancer. So, let’s head to the club and have a martini.’ After 3 or 4 martinis, the two were feeling a little less somber. There were some laughs and more martinis. They were eventually approached by some of the woman’s old friends, who were curious as to what the two were celebrating. The woman told her friends they were drinking to her impending end, ‘I’ve been diagnosed with AIDS.’ The friends were aghast, gave the woman their condolences and beat a hasty retreat. After the friends left, the woman’s daughter leaned over and whispered, ‘Momma, I thought you said you were dying of cancer, and you just told your friends you were dying of AIDS! Why did you do that??’ ‘Because I don’t want any of those bitches sleeping with your father after I’m gone.’.

A guy dies and is sent to hell. Extremely frightened because of that, he is very surprised when he arrives; beach, palm trees, sun is shining, happy people around in shorts and bikinis. Behind the next corner there are people eating great food and there's some cool music playing. After some time of wondering, a man in an expensive suit approaches him and says: "Hi, you must be the new one. Welcome to hell, I'm the devil. As you're gonna spend eternity here, make yourself comfortable and have a drink. If anything bothers you, always feel free to ask me." The guy still doesn't really understand what's going on, this is not what he expected. But finally he decides to inspect the area. Everywhere he goes, there are people laughing and having a great time, there's games, party and fun all around. Then he arrives at a steep cliff that divides the paradise hell from an area underneath, and there is hell as we know it: demons torturing the doomed, there's fire and the smell of brimstone. Shocked, he runs to the devil and says "Devil, how can that be? Here, we have the sweet eternity and down there people are tortured and burned! How can that be?!" The devil laughs and says "Oh, that. That's the Catholics - they want it that way."
