How many U.S. viewers, in millions, are listed for the episode No Tomorrow?

The episode “No Tomorrow” is listed as having 9.61 million U.S. viewers. It is the 12th episode of How I Met Your Mother’s third season and the 56th episode overall, airing on March 17, 2008.

The episode’s St. Patrick’s Day setting drives its central idea: Ted and Barney attend a party while behaving as if there will be no consequences the next day. Ted later reflects on the reckless night, making the title both a plot premise and a joke about impulsive behavior.

The figure is a U.S. audience estimate, not a percentage rating or a worldwide total. A common mix-up is confusing it with the neighboring season-three episodes: “The Platinum Rule” is listed at 8.30 million, while “Ten Sessions” rose to 10.67 million. The 9.61-million figure belongs specifically to “No Tomorrow.”
