The doc told him that masturbating before sex often helped men last longer during the act. The man decided, "What the hell, I'll try it." He spent the rest of the day thinking about where to do it. He couldn't do it in his office. He thought about the restroom, but that was too open. He considered an alley but figured that was too unsafe. Finally, he realized his solution.
He pulled into a deserted parking lot and found a secluded corner. He closed his eyes and began to relieve himself. Just as he got going, he heard a rustling in the bushes nearby. Panicked, he quickly zipped up and turned to see what was there.
To his surprise, he saw a couple of elderly ladies sitting on a park bench. They seemed to be unfazed by what they had just witnessed. One lady turned to the other and said, "You know, Doris, I think we just saw a new kind of flash mob."
