A few months ago, comedy writer Justin Halpern, 29, found himself living at home with his 73-year-old father after being dumped by his longtime girlfriend. Sam Halpern had never minced words, and when Justin moved back home, he was smart enough to write down all the ridiculous things his dad said to him, like “The universe does not give a fuck about you. You are a speck in its shit,” and “The worst thing you can be is a liar....Okay fine, yes, the worst thing you can be is a Nazi, but THEN, number two is liar. Nazi 1, Liar 2,” and “Everybody loves that Da Vinci code book. Bullshit, it sucks. I read it. It’s for all the dummies.” These quotes, or philosophies, have become “Shit My Dad Says,” a Twitter page that in less than a month was being followed by over 500,000 people, had spawned articles in newspapers and magazines, as well as inspiring calls from movie and television producers, celebrities, and just about everyone else who heard about the site.
