Translated from Finnish
So, there is this Swedish inventor who lives in Finland. He's just invented an engine that doesn't run only on regular gas, but also works on Vaseline. He decides to pop it in his car and drive to the town to get it patented.
Meanwhile, a family has just finished eating its dinner elsewhere and is arguing about who should do the dishes.
"I cooked the dinner, therefore I shouldn't be the one washing", says the mother.
"I did the dishes last time, not this time again", reasoned the daughter.
"You're the women of the house, I'm not supposed to do your work!" yelled the father.
After a while, the solution for this dispute was found: All three agreed to take off their clothes and lie perfectly still, naked on the kitchen floor. Whoever was the one to move or do pretty much anything the first had to do the dishes.
Meanwhile our Swedish inventor's car had just run out of fuel in the middle of the journey. "Damn it", he cursed, "I should've made sure I had refueled it before I left. Oh well, I should start walking and look for fuel somewhere", he came to a conclusion.
He saw a house with lights on nearby and walked there to see if they had any gas. He arrived to the front door and knocked several times without getting an answer. He gently opened the door and stepped inside.
"Hello", the inventor yelled, "My car ran out of fuel and I was wondering if you had any to spare?"
Without any response, he ended up in the kitchen in which waited a rather abnormal sight: a man, a woman and a younger woman, all three lying naked on the floor on their backs, doing absolutely nothing. "Do you have any fuel?" the Swedish inventor asked. No response.
So, regardless of this odd situation, he decided to start looking for fuel himself. After a while of searching here and there, he couldn't help noticing the immerse beauty of the daughter of the family. He was, after all, a bit horny so he figured out this was the perfect situation to relieve some stress and thus fucked the daughter. After he was done, he realized: "A-ha! Of course the fuel must be stored in the garage!"
No dice. The inventor searched the garage through and through without finding a single drop of gasoline. Ending up back in the kitchen, he saw that the naked mother of the family wasn't too bad looking either. So, naturally: a quick fuck for her too. After having raped 2/3 of the still-limp family and not finding any gasoline anywhere, he pondered for a while and realized that he wasn't driving a regular car, but the one he had enhanced.
So, he asked: "Do you guys have any Vaseline?"
...after which the father of the family springed up and shouted in terror:
"OH DEAR GOD NO, I'LL DO THE DISHES!"
