"How to Be a Gentleman" is a comedy about the unlikely friendship between a traditional, refined writer and an unrefined personal trainer. Andrew Carlson (David Hornsby) is an etiquette columnist whose devotion to ideals from a more civilized time has lead to a life detached from modern society. Infectiously optimistic, Bert Lansing (Kevin Dillon) is a reformed "bad boy" from Andrew's past who inherited a fitness center, but can still be rude, loud and sloppy.
