Having to move back home at the age of 28 almost universally signals defeat. Images of an unemployed, not-so-well-adjusted George Costanza character from “Seinfeld” might spring to mind.

In Justin Halpern’s case, moving from Los Angeles to his parents’ house in San Diego planted the seeds for a Twitter page that’s quickly growing into an Internet phenomenon, attracting offers from literary agents and book publishers.

Once a day, Halpern, 28, posts a memorable quote that his dad, Samuel, had said the day before. More than 200,000 users subscribe to get their daily dose of Sam.

I first found out about @shitmydadsays on Twitter from Dwight Silverman’s tweet. What’s remarkable is how many A-list Twitterers recommend it (as noted in the article). As I’m writing this post, the account has 28 tweets, yet 236,701 followers.
