The sage advice, “Don’t try this at home,” certainly applies to “I Faked My Own Death” (9 p.m., Discovery), a new three-part series about people driven to extremes.

Cinematic re-enactments show several bizarre schemes, including one man who robbed a body to perpetrate his fraud and another who parachuted from a burning plane.
