I know many will (likely rightfully) say "The bullet", but my personal one is "Golden Time". (Which meant the hours (after regular working hours) when a plumber, which is who Mr. Haines played, can charge a higher rate.) I can think of maybe a couple other RMT actors who would have made good plumbers (Joe Julian, for example), but none who could have you feeling as sorry for him, witnessing a drug deal while merely trying to do his job, fearing/running for his life, and having a happy ending, as Haines did in "Golden Time". IMO.
