The Bachelors is a group created by Gammie Heffley. The group consists of every male member of the Heffley Family who are single, or "bachelors". They all have to sleep in a single room at Gammie's home at family gatherings or events, such as Uncle Gary's wedding.
Four members sleep on two beds, while the rest bundle up on the floor in sleeping bags.
