Well, the guy tried it and it worked like a charm. So he kept a small can of Vasoline in his pocket wherever he went with the bike.
Now it gets interesting.
He had a new girlfriend and she invited him to dinner at her house for him to meet her parents. She warned him, though: "My dad is old but he was a career military man and he's very strict at the dinner table. NO ONE CAN SAY A WORD during dinner or until we leave the table, my dad leaves the table first. Anyone who talks has to WASH THE DISHES." The guy thought it kinda weird but hey, he was up for a challenge. So he rode his Harley to her house that night.
He met the parents, the old man was crusty but he was surprised to see that the mother was much younger, in her early 40s, fit and gorgous. But when they passed by the kitchen he was horrified to see that there were dishes in the sink stacked all the way to the ceiling. There were also several piles of dishes on the floor stacked to the ceiling. He was determined not to say a word during dinner. During dinner no one said a word. Even the pets were quiet. It felt weird and the guy was getting bored. So he decided to have a little fun with the situation. He looked at his girlfriend and winked at her, he jumped across the table, grabbed her, and had wild sex with her right on the table, all without saying a word.
No one said a word.
When they finished, he looked at her mom and decided she looked so good, he grabbed her and did the same.
No one said a word.
When they finished, he looked at the old man and couldn't believe that he didn't say anything. Right then he heard thunder outside and the pitter-patter of rain. He remembered about his Harley in the driveway so he pulled out his can of Vasoline and put it on the table.
Immediately the old man stood up and said "I'll do the dishes."
