Income tax

One day, a man named Tony died. When he was sent to be judged, he was told that he had committed a sin, and that he could not go to heaven right away.
He asked what he did and God told him that he cheated on his income taxes, and the only way he could get into heaven would be to sleep with a 500 pound, stupid, butt-ugly woman for the next five years and enjoy it. Tony decided that this was a small price to pay for an eternity in heaven. So off he went with this enormous woman, pretending to be happy.
As he was walking along, he saw his friend Carlos up ahead. Carlos was with an even bigger, uglier woman than he was with. When he approached Carlos, Tony asked him what was going on. Carlos replied, "I cheated on my income taxes and scammed the government out of a lot of money... even more than you did." They both shook their heads and figured that, as long as they have to be with these women, they might as well hang out together to help pass the time.
Now Tony, Carlos and their two beastly women were walking along one day, minding their own business when Tony and Carlos could have sworn they saw their friend John up ahead, only this man was with an absolutely drop dead gorgeous supermodel-centerfold woman. Stunned, Tony and Carlos approached the man and in fact, it was their friend John. They asked him how is it that he is with this unbelievable goddess, while they were stuck with these digustingly awful women.
John replied, "I have no idea and I'm definitely not complaining. This has been positively the best time of my life (and I'm dead!) and I have five years of the best sex any man could hope for to look forward to. There is only one thing I can't seem to understand. Every time after we have sex, she rolls over and murmurs to herself "Damn income taxes!"
