There was a hotdog. The problem is that the hotdog was never loved. He was the smallest hotdog. Frank had the biggest buns though. He'd never get eaten because of his size. When Frank looked at other hotdogs getting eaten, he was saddened by the lack of girth and juiciness he had. Even though there was sadness, he loved seeing wieners getting shoved into people's mouths. It was a big fantasy of his. So instead of being the smallest, he inverted himself. His big fat buns made himself vagina. The labia to be exact. Frank then rubbed his wiener against the buns. Pleasuring himself. Even used ketchup as the lubricant. He realized that he didn't need to be swallowed anymore. Frank was content with himself. Big buns and all.
