Brigham Young University, the private school affiliated with the Mormon church, has no qualms about being ranked the most "stone-cold sober" college for the 18th year in a row.

Princeton Review released their annual college rankings on Monday, naming both the most sober and the biggest party schools . BYU has made milk-based jokes on social media in recent years to celebrate their crowning as the school least likely to party, and did so again this year.

The "stone-cold sober" ranking is often dominated by religious and military schools, as well as campuses from the City University of New York system. Religious and military colleges are often more strict about rules on student conduct, like their prohibition of alcohol and drugs, while CUNY schools typically lack the residential campus many larger state universities have.
