Thor, the Viking God of Thunder, and his pal Odin were up in Valhalla, when suddenly Thor said to Odin, "It's been a long time now. I really need to have sex." Odin stood and pondered for a while, before replying, "Go to Earth, O Thor, and find thyself what they call a "lady of joy" and treat her to your manly pleasures." And this Thor did. The next day, he came back up to see Odin, and told him of the previous night's events. "My friend," he said, grinning from ear to ear, "It was wonderful. We had passionate sex 37 times.." "37 times!" exclaimed Odin. "That poor woman! Mere mortals cannot endure such treatment. You must go and apologize this instant!" So Thor went back down to earth and found the aforementioned prostitute, saying. "I'm sorry about last night, but you see, I'm Thor..." "You're Thor?" shouted the girl. "You're Thor? What about me? I'm tho thor I can hardly pith!"
