As she left the bank, a woman stood in some doggy doo. She looked around to find somewhere to scrape the mess from her shoe and decided that the curb would do nicely. She leaned on the car parked there and commenced scraping the offending stuff from her shoe.
A moment later a gentleman walked from the same bank and he too stood in the mess. He walked over to the vehicle and proceeded to scrape his shoe on the curb as well.
The woman looked him and said, "Oh yuk, I just did that."
The man glared at the woman and replied, "That's disgusting. I should rub your nose in it."
