Cherif is a French detective in Lyon who is obsessed with American cop shows, particularly 70's kitsch shows like Starsky and Hutch; Colombo; Mannix; Mission Impossible, etc. He constantly uses strategies from these shows in solving cases, and knows them so well he can cite the season and episode. Yesterday he got bonked on the head and Huggy Bear from Starsky and Hutch showed up. Nobody else could see him, but HB kept giving Cherif advice so his coworkers thought he was nuts since he was constantly dealing with someone who they couldn't see. This was pretty entertaining. The actor who played Huggy Bear--Antonio Fargas-- is still alive and well at 77.
